N-Acyl-1-methyl-omega-phenylalkylamines predominantly in the form of the R enantiomer, are prepared by a process using a biocatalyst capable of stereoselectively hydrolysing the N-acyl group of the S enantiomer and recovering the remaining N-acyl-1-methyl-omega-phenylalkylamine predominantly in the form of the R enantiomer. The S enantiomer may be hydrolysed to yield the S enantiomer of the corresponding amine, which may be recovered.
主要以 R 对映体形式存在的 N-酰基-1-甲基-ω-苯基烷基胺,是通过使用一种生物催化剂制备的,该催化剂能够立体选择性地水解 S 对映体的 N-酰基,并回收剩余的主要以 R 对映体形式存在的 N-酰基-1-甲基-ω-苯基烷基胺。S 对映体水解后可得到相应胺的 S 对映体,并可回收。

Optimization of the kineticresolution of 2-amino-4-phenyl-butane was achieved at 80 °C using CAL-B-catalyzed aminolysis of carboxylic acids and their ethyl esters. The reactions carried out with long chain esters and the corresponding acids as acyldonors proceeded with remarkably high enantioselectivity. The use of carboxylic acids as acylating agents led to a marked acceleration of the reaction
