In one aspect, the present invention relates to a process for the preparation of an optically active alcohol of formula
or its mirror image, wherein R
1
is unsubstituted or substituted heteroaryl and R
2
is phenyl or substituted aryl, by asymmetrically hydrogenating the corresponding ketones in the presence of specific platinum metal complex catalysts, particularly ruthenium.
在一个方面,本发明涉及一种制备式为或其镜像的手性醇的过程,其中R1未被取代或被取代的杂环烷基,R2为苯基或取代芳基,通过在特定
铂金属配合物催化剂的存在下不对称氢化相应的酮来实现。特别是采用
钌作为催化剂。
