Title:
【発明の名称】触媒によりエナンチオ選択的にケトンを還元する方法
Document Type and Number:
Japanese Patent JP2001504127
Kind Code:
A
Abstract:
The invention involves a procedure for the catalytic enantioselective reduction of ketones to chiral alcohols. Heretofore, this reaction was carried out batch-wise. Because, in this procedure, one utilizes a catalyst increased in size with polymer, it is possible to carry out the reaction in a quasi-continuous manner in a membrane reactor. In contrast to the state of the art, one thus dramatically increases the operative life of the catalyst.
