Highly enantioselective chiral aminolysis of cis-4-cyclohexen-1,2-ylenebis(carboxylic acid) anhydride has been performed by employing sodium salt of 4(R)-isopropyl-1,3-thiazolidine-2-thione in THF-DMSO.Other chiral aminolyses of prochiral ?-symmetric dicarboxylic anhydrides such as cis-cyclobutan-1,2-ylenebis(carboxylic acid) anhydride, meso-2,4-dimethylglutaric anhydride, and 3-glutaric anhydride were similarly investigated.
