Described is a process for the biotechnological resolution, by means of stereoselective enzymatic esterification, of the racemic mixture of optical isomers of tosyloxy-alkanols of general formula (I):
wherein R represents an alkyl, haloalkyl or C2-Cio alkenyl group, either linear or branched, and n is 1 or 2, by using aliphatic acid anhydrides in the presence of an enzyme which is capable of selectively catalyzing the esterification of the (R) isomer, leaving the (S) isomer basically unchanged.
本发明描述了一种通过立体选择性酶法酯化,以
生物技术解决通式(I)的对羟基烷 醇光学异构体外消旋混合物的工艺:
其中 R 代表直链或支链烷基、卤代烷基或 C2-Cio 烯基,n 为 1 或 2,使用脂肪族酸酐,在一种酶的存在下,该酶能选择性地催化(R)异构体的酯化反应,而(S)异构体基本不变。
