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。
