Lipase-catalyzed kinetic resolution of threo -configured 1,2-diols: a comparative study of transesterification versus hydrolysis
摘要:
The kinetic resolution of the alpha,beta-unsaturated vicinal diols 3 has been investigated by irreversible transesterification in organic media and by hydrolysis of the corresponding diacetates 6 (Scheme 1). The best results were obtained in the hydrolysis of the diacetates with the lipase CAL-B from Candida antarctica as a catalyst. (C) 1998 Elsevier Science Ltd. All rights reserved.
