Novel Chiral Aziridine Phosphoramidate Compounds
The invention includes processes for the synthesis of amphetamine, dexamphetamine, methamphetamine, derivatives of these, including their salts, and novel precursors and intermediates obtained thereby, by synthesizing aziridine phosphoramidate compounds in specified solvents at specified temperatures, and then converting to a novel aryl or aryl-alkyl phosphoramidate precursors using an organometallic compound such as a copper salt, where the novel aryl or aryl-alkyl phosphoramidate precursor is then easily converted to the target compounds using known reactions,
Chiral aryl or aryl-alkyl phosphoramidate dexamphetamine precursors having a regioisomeric purity >99%

A DEUTERATED COMPOUND, AND PREPARATION METHOD AND USE THEREOF
Described is a deuterated compound, and preparation method and use thereof. The deuterated compound I has a structure as shown in Formula (I), wherein A is H or D, and at least one of eight As is D; M is H or an alkali metal, an alkaline earth metal, or an ammonium radical. The present invention provides use of the deuterated compound I as an internal standard for measuring the content of a metabolite II in a biological sample, wherein the metabolite II has a structure as shown in a Formula (II); wherein A is H; M is H or an alkali metal, an alkaline earth metal, or an ammonium radical. The present invention uses the deuterated compound I as an internal standard to quantitatively analysis the content of metabolite II at lower content in biological samples, which can not only meet the requirements for the lower limit of quantitation, but also meet the requirements for DMPK studies in clinical trials.

Fluorine-containing compound and anti-cancer medical use thereof
Described is a fluorine-containing compound shown in Formula II/III and its anti-cancer medical use. The present application creatively introduced the fluorine-containing groups such as special trifluoromethyl groups, fluorine-substituted aryl groups, or heteroaryl groups at special positions (such as the position between the nitrobenzene ring and the phosphate amine group) in the structures of the above compounds. After this modification, it was found that all of the resulting compounds were solids (including waxes). ##STR00001##
