Method for preparing (S) -2-chloro-1- (3, 4-difluorophenyl) ethanol |
| abstract |
The invention provides a method for preparing (S) -2-chloro-1- (3, 4-difluorophenyl) ethanol, which comprises the following steps: immobilizing keto reductase KRED by using an immobilized carrier LX-1000ODS or LXES-J420 to obtain an immobilized enzyme; catalyzing 2-chloro-1- (3, 4-difluorophenyl) ethanone by using immobilized enzyme to perform reduction reaction to obtain a target compound. The method can efficiently and stably catalyze the substrate reaction to generate a product with high optical purity, and is suitable for industrial application. |
