  5. Abstract : a novel enzymatic reaction ? ammonolysis was introduced in thenineties. this reaction not only provides a synthetically useful and mild alternative method for the synthesis of amides, but also can be used for the kinetic resolution of chiral alcohols or chiral carboxylic acids. in addition to enantioselective hydrolysis, esterification and transesterification, ammonolysis also shows high enantioselectivity in the resolution of racemates
