Stereospecificaily deuteriated isoserines 4, formed from enzymically prepared 3-deuteriated malic acids 2(X = OH) by Curtius rearrangement, have been converted to the deuteriated aziridines 7 and 9 which, on ring-opening and deprotection, yielded samples of the amino acids D-serine and D-cystine and the enzyme inhibitor–substrates D-β-chloroalanine and D-serine O-sulphate which are labelled Stereospecificaily at C-3 with deuterium.
由酶法制备的 3-去甲基苹果酸 2(X = OH)通过 Curtius 重排生成的立体特异性去甲基异丝氨酸 4 被转化为去甲基氮丙啶 7 和 9,经开环和脱保护后,可得到 D-丝氨酸和 D-胱氨酸氨基酸样品以及酶抑制剂-底物 D-β-氯丙氨酸和 D-丝氨酸 O-硫酸盐,这些样品的 C-3 处均用氘进行了立体特异性标记。
