Enzyme catalysed hydrolyses of dialkylated propanedioic acid diesters have been studied. A novel change of enantioselectivity from pro-S to pro-R in the hydrolysis of ester groups was observed, depending on the chain length of the alkyl substituents of the substrate. Optically pure (S)-(-)-α-methylphenylalanine was prepared by α-chymotrypsin catalysed hydrolysis of benzylmethylpropanedioic acid dimethyl
已经研究了二烷基化丙二酸二酯的酶催化水解。观察到在酯基水解中从前-S到前-R的对映选择性的新变化,这取决于底物的烷基取代基的链长。通过α-胰凝乳蛋白酶催化的苄基甲基丙二酸二甲酯的水解制备光学纯的(S)-(-)-α-甲基苯基丙氨酸。
