DERIVATIVES OF SOBETIROME
Disclosed are halo substituted derivative compounds of sobetirome with improved pharmacological characteristics relative to sobetirome, pharmaceutical compositions that include those compounds and methods of treating diseases such as neurodegenerative disorders using those pharmaceutical compositions.
Synthesis of fluorinated radiopharmaceuticals via electrochemical fluorination
Provided herein are methods and compositions for the electrochemical selective radiofluorination of aromatic molecules. The resulting fluorine-18 labeled compounds are ideal radionuclides for use in Positron Emission Tomography (PET); they are also difficult to radiolabel efficiently and with high specific activity using existing approaches. For example, radiopharmaceuticals such as [F18]L-DOPA, which is indispensable in PET brain disease imaging, may be made electrochemically with high radiochemical yield and high specific activity using 18F-. The invention process described herein opens new possibilities and provides wider access to PET tracers such as 18F-L-Dopa, since 18F- is much more widely available than the 18F.sub.2, currently used for synthesis of electron rich substrates.

2-POSITION MODIFICATION FOR SYNTHESIS OF RESORCINOL SCAFFOLDING
A resorcinol with modifications at the 2-position is provided. The reactant resorcinol may have a variety of functional groups at each of the 1, 3, and 5 position such as a hydroxide, a lower alkyl group, a phenyl, a substituted phenyl, a lower alkenyl, or a lower alkynyl sp.sup.2 carbon group (e.g., substituted phenyl, vinyl), sp (e.g., alkyne), hydrogen. The resorcinol is modified at the 2-position with a nucleophile or an electrophile. The resulting resorcinol may serve as a stable intermediate for the synthesis of cannabinoid or cannabinoid derivatives.

Access to chiral bisphenol (BPOL) ligands through desymmetrizing asymmetric ortho-selective mono-halogenation
The subject invention pertains to a method of halogenating phenols, yielding a range of halogenated phenols with enantiomeric ratio of up to 99.5:0.5. In certain embodiments, the subject invention pertains to a method of asymmetric halogenation of bisphenol, yielding a range of chiral bisphenol ligands. The novel chiral bisphenols are potent privileged catalyst cores that can be applied to the preparation of ligands for various catalytic asymmetric reactions. The catalyst library can easily be accessed because late-stage modification of the scaffold can readily be executed through cross-coupling of the halogen handles on the bisphenols.
