Description

DETAILED DESCRIPTION

[0041] The following description of the disclosure is provided as an enabling teaching of the disclosure in its best, currently known embodiments. Many modifications and other embodiments disclosed herein will come to mind to one skilled in the art to which the disclosed compositions and methods pertain having the benefit of the teachings presented in the foregoing descriptions. Therefore, it is to be understood that the disclosures are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. The skilled artisan will recognize many variants and adaptations of the aspects described herein. These variants and adaptations are intended to be included in the teachings of this disclosure and to be encompassed by the claims herein.

[0042] Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.

[0043] As can be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.

[0044] Any recited method can be carried out in the order of events recited or in any other order that is logically possible. That is, unless otherwise expressly stated, it is in no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not specifically state in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow, plain meaning derived from grammatical organization or punctuation, or the number or type of aspects described in the specification.

[0045] All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided herein can be different from the actual publication dates, which can require independent confirmation.

[0046] It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosed compositions and methods belong. It can be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0047] Prior to describing the various aspects of the present disclosure, the following definitions are provided and should be used unless otherwise indicated. Additional terms may be defined elsewhere in the present disclosure.

Definitions

[0048] As used herein, comprising is to be interpreted as specifying the presence of the stated features, integers, steps, or components as referred to, but does not preclude the presence or addition of one or more features, integers, steps, or components, or groups thereof. Moreover, each of the terms by, comprising, comprises, comprised of, including, includes, included, involving, involves, involved, and such as are used in their open, non-limiting sense and may be used interchangeably. Further, the term comprising is intended to include examples and aspects encompassed by the terms consisting essentially of and consisting of. Similarly, the term consisting essentially of is intended to include examples encompassed by the term consisting of.

[0049] As used in the specification and the appended claims, the singular forms a, an and the include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a compound, a base, or a solvent, includes, but is not limited to, two or more such compounds, bases, solvents, and the like.

[0050] It should be noted that ratios, concentrations, amounts, and other numerical data can be expressed herein in a range format. It can be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as about that particular value in addition to the value itself. For example, if the value 10 is disclosed, then about 10 is also disclosed. Ranges can be expressed herein as from about one particular value, and/or to about another particular value. Similarly, when values are expressed as approximations, by use of the antecedent about, it can be understood that the particular value forms a further aspect. For example, if the value about 10 is disclosed, then 10 is also disclosed.

[0051] When a range is expressed, a further aspect includes from the one particular value and/or to the other particular value. For example, where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, e.g. the phrase x to y includes the range from x to y as well as the range greater than x and less than y. The range can also be expressed as an upper limit, e.g. about x, y, z, or less and should be interpreted to include the specific ranges of about x, about y, and about z as well as the ranges of less than x, less than y, and less than z. Likewise, the phrase about x, y, z, or greater should be interpreted to include the specific ranges of about x, about y, and about z as well as the ranges of greater than x, greater than y, and greater than z. In addition, the phrase about x to y, where x and y are numerical values, includes about x to about y.

[0052] It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a numerical range of about 0.1% to 5% should be interpreted to include not only the explicitly recited values of about 0.1% to about 5%, but also include individual values (e.g., about 1%, about 2%, about 3%, and about 4%) and the sub-ranges (e.g., about 0.5% to about 1.1%; about 5% to about 2.4%; about 0.5% to about 3.2%, and about 0.5% to about 4.4%, and other possible sub-ranges) within the indicated range.

[0053] As used herein, the terms about, approximate, at or about, and substantially mean that the amount or value in question can be the exact value or a value that provides equivalent results or effects as recited in the claims or taught herein. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art such that equivalent results or effects are obtained. In some circumstances, the value that provides equivalent results or effects cannot be reasonably determined. In such cases, it is generally understood, as used herein, that about and at or about mean the nominal value indicated 10% variation unless otherwise indicated or inferred. In general, an amount, size, formulation, parameter or other quantity or characteristic is about, approximate, or at or about whether or not expressly stated to be such. It is understood that where about, approximate, or at or about is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.

[0054] As used herein, the terms optional or optionally means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

Chemical Definitions

[0055] Compounds are described using standard nomenclature. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of skill in the art to which this invention belongs.

[0056] The compounds described herein include enantiomers, mixtures of enantiomers, diastereomers, tautomers, racemates and other isomers, such as rotamers, as if each is specifically described, unless otherwise indicated or otherwise excluded by context.

[0057] A dash (-) that is not between two letters or symbols is used to indicate a point of attachment for a substituent. For example, (CO)NH.sub.2 is attached through the carbon of the keto (CO) group.

[0058] The term substituted, as used herein, means that any one or more hydrogens on the designated atom or group is replaced with a moiety selected from the indicated group, provided that the designated atom's normal valence is not exceeded and the resulting compound is stable. For example, when the substituent is oxo (i.e., O) then two hydrogens on the atom are replaced. For example, a pyridyl group substituted by oxo is a pyridine. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds or useful synthetic intermediates. A stable active compound refers to a compound that can be isolated and can be formulated into a dosage form with a shelf life of at least one month. A stable manufacturing intermediate or precursor to an active compound is stable if it does not degrade within the period needed for reaction or other use. A stable moiety or substituent group is one that does not degrade, react or fall apart within the period necessary for use. Non-limiting examples of unstable moieties are those that combine heteroatoms in an unstable arrangement, as typically known and identifiable to those of skill in the art.

Unless indicated otherwise, parts are parts by weight, temperature is in degrees Celsius or is at ambient temperature, and pressure is at or near atmospheric pressure.

General Experimental.

[0268] Reagents were purchased at the highest commercial quality and used without further purification, unless otherwise stated. Anhydrous diethyl ether (Et.sub.2O), tetrahydrofuran (THF), 2-methyl tetrahydrofuran (2-Me-THF), toluene (PhMe) were obtained by passing the previously degassed solvent through an activated alumina column (PPT Glass Contour Solvent Purification System). Anhydrous cyclopentyl methyl ether (CPME), dimethoxyethane (DME) and methyl tert-butyl ether (MTBE) were purchased from Acros Organics. All glassware was flame-dried under vacuum before use. Yields refer to chromatographically and spectroscopically (.sup.1H NMR) homogeneous material, unless otherwise stated. Reactions were monitored by LC-MS or thin layer chromatography (TLC) carried out on 250 m SiliCycle SiliaPlates (TLC Glass-Backed TLC Extra Hard Layer, 60 ), using shortwave UV light as the visualizing agent and p-anisaldehyde, phosphomolybdic acid (PMA) or KMnO.sub.4 with heat as developing agents. Flash column chromatography was performed with a Biotage Isolera One (ZIP or SNAP Ultra cartridges) or with traditional glass flash columns using SiliCycle SiliaFlash P60 (particle size 40-63 m). NMR spectra were recorded on a Bruker Ascend 500 MHz instrument or Bruker Neo600 600 MHz spectrometer and were calibrated using residual undeuterated solvent as an internal reference (CDCl.sub.3: 7.26 ppm .sup.1H NMR, 77.16 ppm .sup.13C NMR; DMSO-d6:2.50 ppm .sup.1H NMR, 39.5 ppm .sup.13C NMR). The following abbreviations were used to explain NMR peak multiplicities: s=singlet, d=doublet, t=triplet, q=quartet, dd=doublet of doublet, ddd=doublet of doublet of doublet, dddd=doublet of doublet of doublet of doublet, ddddd=doublet of doublet of doublet of doublet of doublet, tt=triplet of triplet, ddt=doublet of doublet of triplet, m=multiplet, br=broad, hept=heptet. High resolution mass spectra (HRMS) were recorded on an Agilent 6230 LC-MS TOF mass spectrometer. Enantiomeric excess (ee) was determined using a Varian Prostar HPLC with a 210 binary pump and a 335 diode array detector. Optical rotations were measured using a JASCO P-2000 polarimeter with a cell length of 1 dm. Melting points were recorded on a Chemglass DMP 100 melting point apparatus and were uncorrected.

Handling of Reagents.

[0269] All synthesized sulfonimidoyl fluorides were stored under ambient conditions, either room temperature or at 20 C. Notably, there is no significant difference observed regarding to reactivity and stereospecificity. Specifically for the t-BuSF, NMR tests demonstrated it is stable for at least 7-month under ambient conditionsin other words, it is bench stable. Sulfoximines and sulfonimidamides were stored under ambient conditions and appeared to be unchanged over the course of this work.

##STR00056##

[0272] In a septum capped 1 L round-bottomed flask equipped with a stir bar and argon balloon was added (R)-sulfinamide (10.3 g, 41.4 mmol, 1 eq.) and THF (400 mL, 0.21 M) then cooled to 0 C. NaH (8.50 g, 212 mmol, 2.5 eq., 60% wt) was added portion-wise (3 portions) then stirred for 20 minutes until H.sub.2 gas evolution ceased. DIPC-CCI (13.9 g, 84.9 mmol, 1 eq.) was added portion-wise (3 portions) then stirred at 0 C. for 1.5 hours until H.sub.2 gas evolution ceased (reaction monitored by TLC and LC-MS for the disappearance of sulfinamide). NFSI (28.1 g, 89.2 mmol, 1.05 eq.) was added in one portion then stirred at 0 C. for an additional 1 hour (reaction monitored by TLC and LC-MS for the disappearance of sulfinyl urea intermediate). The reaction mixture was removed from the ice bath and diluted with 10% EtOAc in hexanes (300 mL) then filtered through a medium porous sintered glass funnel while rinsing with 10% EtOAc in hexanes. The organic solution was washed with 10% KI aqueous solution (150 mL3: for removal of unreacted NFSI) and brine (150 mL3). The solvent was dried over anhydrous Na.sub.2SO.sub.4, filtered and solvents removed under reduced pressure to give a yellow oil. Further purification by silica gel column chromatography using hexanes/EtOAc (0% to 20% EtOAc) provided the desired sulfonimidoyl fluoride (19.8 g, 74.3 mmol, 87% yield) as a clear colorless oil that solidified to a white crystalline solid under reduced pressure.

Stability Experiments for t-BuSF Reagent
Bench Stability Analysis of t-BuSF.

[0274] The t-BuSF used for the stability study was prepared following the general procedure and stored on the lab bench in a capped 20 mL colorless vial at ambient temperatures. Room temperature was variable (23-26 C. and humidity was roughly 55%). t-BuSF samples were prepared from the same batch, separated into 3 different vials and compared with freshly prepared material. Stability analysis using .sup.1H-NMR, .sup.19F-NMR and .sup.13C-NMR were used and accompanied by a reaction performance analysis (% yield and % ee) using phenyl lithium as the nucleophile.

[0275] Based on the NMR analysis, no significant decomposition was observed. The only identifiable peaks were that of diisopropyl amine (presumably forms via decomposition pathway). Reaction performance analysis provided identical enantiopurity of products with slightly diminished yields (up to 10%).

Thermal Stability of Tert-Butyl Sulfonimidoyl Fluoride Reagents.

[0276] An analysis of thermal stability of t-BuSF was performed and compared to other protected t-Bu sulfonimidoyl fluorides. Three different solvents were used for a thermal distribution of 35-110 C. Each sample (0.2 mmol, 0.1 M) was refluxed in the respective solvent: Et.sub.20 (35 C.), THF (66 C.) and toluene (110 C.) for 24 hours. Note: anhydrous solvents and conditions were not employed. After 24 hours of heating, the reactions were cooled to room temperature, the solvent was removed under reduced pressure, and the remaining residue dissolved in CDCl.sub.3 then analyzed by NMR (1H and 1 F.).

Thermal Stability of t-BuSF.

[0277] Based on the NMR analysis of t-BuSF, significant decomposition was only observed when heating at 110 C. in toluene for 24 hours. We were unable to identify the by-products besides diisopropyl amine. Decomposition was not observed at room temperature in either of the solvents used.

Thermal Stability Comparison of Different Protecting Groups.

[0278] Four different protecting groups were evaluated for thermal stability: two urea-based (CON(i-Pr).sub.2, CONEt.sub.2) one carbamate (-Boc) and one acyl (-Piv). Other protecting groups including silyl (-TBS, -TBDPS), -tosyl, and -benzyl were unable to be prepared and evaluated due to reactivity or stability issues of the sulfinamide precursors and/or sulfonimidoyl fluoride products.

##STR00057##

[0279] Experimental procedures and analyses were identical to those described above for the t-BuSF reagent. .sup.1H NMR was found to provide greater diagnostic evidence of decomposition compared to 19F NMR. The urea protecting groups were both found to have increased stability under the thermal conditions relative to carbamate and acyl protecting groups. Both -Boc and -Piv protecting groups exhibited significant decomposition after refluxing (66 C.) in THF for 24 hours. No obvious decomposition was observed when refluxing (35 C.) in Et.sub.2O for 24 hours across all four protected sulfonimidoyl fluorides.

Recrystallization of Tert-Butyl Sulfoximines to Further Enhance Enantiopurity.

[0300] For the cases in which organolithium additions to t-BuSF do not give the desired enantiopurity, recrystallizations can be performed to further enhance the enantiopurity of tert-butyl sulfoximines. We have found that nearly all N,N-diisopropyl urea protected chiral tert-butyl sulfoximines prepared from t-BuSF are solids at room temperature and have the potential to further enhance the enantiopurity if desired.

[0301] For example: tert-butyl phenyl sulfoximine was used as our model substrate to demonstrate the bifunctional property of the t-BuSF sulfonimidoyl transfer reagents. The addition of PhLi (commercial or in situ generated) to t-BuSF provides tert-butyl phenyl sulfoximine in 98% ee as a white solid which was enhanced to >99% ee via recrystallization.

[0302] The general procedure (GP-14) for typical recrystallizations is as follows: Pure tert-butyl sulfoximine was dissolved in a minimum amount of acetone, with the help of ultrasonic bath or heat. Hexanes (three times the volume of acetone used) was slowly added to prevent complete mixing of the two solvents. The mixture was transformed to 20 C. freezer to settle overnight to induce recrystallization. After 12 hours the recrystallized material was collected by filtration and washed with hexanes (3) to give 60-70% recovery yield and >99% ee after a single recrystallization. This process can be repeated two more times to give up to 90% recovery yield with >99% ee.

Other Examples

[0304] tert-butyl 4-chlorophenyl sulfoximine (>90% recovery, 95 to >99% ee; three crops).
