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
文摘:酶促氨解反應是20世紀90年代中期發現的一種新型反應，在脂肪酸酰胺的合成、手性藥物（手性酸及手性醇等）的拆分中顯示出巨大的應用潛力，是除立體選擇性水解、酯化、轉酯反應之外的另一具有較大開發應用前景的酶促新型反應。 -
