The pH dependence of the α-chymotrypsin-catalyzed hydrolysis of dimethyl 3-hydroxyglutarate (3) has been studied. The e.e. was determined by HPLC analysis of diastereoisomeric camphanoic-acid derivatives. Kinetic resolution of the β,α-epoxy esters 10 and 24 by pig liver esterase has been shown to provide an alternative access to chiral β-hydroxy esters and acids of high optical purity. By this latter
已经研究了α-胰凝乳蛋白酶催化的3-羟基戊二酸二甲酯(3)水解的pH依赖性。ee通过非对映异构樟脑酸衍生物的HPLC分析确定。已经显示猪肝酯酶对β,α-环氧酯10和24的动力学拆分提供了对手性β-羟基酯和高光学纯度的酸的替代途径。通过后一种方法,合成了γ-氨基-β-羟基丁酸(GABOB)的非天然对映异构体。最后,用猪肝酯酶将内消旋-3,4-环氧己二酸二甲酯(19)选择性几乎水解。
