Preparations of optically active N-hydroxytartrimides were achieved. 1,3,4-Trihydroxysuccinimide ester of Z-L-alanine and 1-hydroxy-3,4-diacetoxysuccinimide ester of Z-D-alanine were allowed to react with D,L-alaninate to produce L-L form and D-D form of Z-Ala-Ala-OEt respectively (optical yield 100%).
制备了光学活性的N-羟基酒石酰亚胺。使ZL-丙氨酸的1,3,4-三羟基琥珀酰亚胺酯和ZD-丙氨酸的1-羟基-3,4-二乙酰氧基琥珀酰亚胺酯与D,L-丙氨酸酯反应以生成LL-形式和DD-形式的Z-Ala-Ala -OEt分别(光学收率100%)。
