Latest Patents

One of Jianfeng Hang's latest patents focuses on the kinetic resolutions of chiral 2- and 3-substituted carboxylic acids. This invention outlines a method for the kinetic resolution of racemic and diastereomeric mixtures of chiral compounds. The critical elements of this method include a non-racemic chiral tertiary-amine-containing catalyst, a racemic or diastereomeric mixture of a chiral substrate, such as a cyclic carbonate or cyclic carbamate, and a nucleophile, which can be an alcohol, amine, or thiol. A preferred embodiment of this invention aims to achieve the kinetic resolution of racemic and diastereomeric mixtures of derivatives of α- and β-amino, hydroxy, and thio carboxylic acids. In certain embodiments, the methods achieve dynamic kinetic resolution, wherein the yield of the resolved enantiomer or diastereomer exceeds the amount present in the original mixture due to the in situ equilibration of the enantiomers or diastereomers under the reaction conditions prior to the resolution step.
