The present invention relates to a process of the asymmetric hydrogenation of a ketal of an unsaturated ketone or an acetal of an unsaturated aldehyde by molecular hydrogen in the presence of at least one chiral iridium complex. This process yields chiral compounds in a very efficient way and is very advantageous in that the amount of iridium complex can be remarkably reduced.
本发明涉及在至少一种手性
铱配合物存在的情况下,通过分子氢对不饱和酮的
缩酮或不饱和醛的
缩醛进行不对称加氢的方法。该方法以非常高效的方式产生手性化合物,并且非常有利的是
铱配合物的用量可以显著减少。
