The present invention relates to a process comprising hydrolysis or trans esterification of one of the two enantiomeric forms of a racemic or enantiomerically enriched ester of formula I or IV by a higher rate than the other by an enzyme to give an ester and a acid (III) or two different esters (V) and (VI) with different R groups both with increased enantiomeric purity and a esterification process of a racemic or enantiomerically enriched acid (VII) by an enzyme to give an ester and an acid both with increased enantiomeric purity.
本发明涉及一种过程,包括通过酶催化作用使公克混合物或对映富集的酯化合物I或IV的两种对映异构体中的一种
水解或酯交换速率高于另一种,从而得到具有提高对映纯度的酯和酸III或具有不同R基团的两种不同酯V和VI,以及通过酶催化作用酯化公克混合物或对映富集的酸VII,从而得到具有提高对映纯度的酯和酸。
