Process for preparing optically active trans-3-phenylglycidamide compound, which comprises subjecting racemic trans-3-phenylglycidamide compound of the formula (I)
wherein Ring A is substituted or unsubstituted benzene, and R1 is H or lower alkyl, to optical resolution using a microorganism having ability of preferentially hydrolyzing one of (2S,3R) isomer or (2R,3S) isomer thereof, and process for preparing an optically active 1,5-benzothiazepine derivative from the thus-obtained optically active trans-3-phenylglycidamide compound.
制备光学活性反式-3-苯基缩水甘油酰胺化合物的工艺,包括将式(I)的外消旋反式-3-苯基缩水甘油酰胺化合物
其中环 A 是取代或未取代的苯,R1 是 H 或低级烷基,使用具有优先水解(2S,3R)异构体或(2R,3S)异构体中一种异构体能力的微生物进行光学解析,以及用由此获得的光学活性反式-3-苯基缩水甘油酰胺化合物制备光学活性 1,5-苯并硫氮杂卓衍生物的工艺。
