The present intention relates to a method for kinetic resolution of racemates of alcohols with one or several stereogenic centers. The invention is particularly suitable for producing pharmaceutical agents or plant protective agents. According to the invention, first racemic alcohols are converted with fluorinated acylation agents into racemic fluorinated carboxylic acid esters. Subsequently, by lipase-catalyzed reaction of the racemic fluorinated carboxylic acid ester with alcohols the fluorous phase marking of the faster reacting enantiomer is canceled and that of the slower reacting enatiomer is maintained. Subsequently, the enantiomers are extractively separated by distribution between organic phase and fluorous phase.
本发明涉及一种具有一个或多个立体中心的醇的外消旋体的动力学解析方法。本发明尤其适用于生产药剂或植物保护剂。根据本发明,首先用含
氟酰化剂将外消旋醇转化为外消旋含
氟羧酸酯。随后,在
脂肪酶催化下,外消旋含
氟羧酸酯与醇发生反应,反应较快的对映体的荧光相标记被消除,反应较慢的对映体的荧光相标记保持不变。随后,对映体通过在有机相和流相之间的分布进行萃取分离。
