EFFICIENT PROCESS OF ASYMMETRIC HYDROGENATION OF UNSATURATED KETONES USING ADDITIVES

摘要

The present invention relates in the beta-unsaturated ketone of asymmetric hydrogenation or the molecular hydrogen of aldehyde at least one chiral complex of iridium and at least one additive and halohydrin. The process generates chiral compound in an efficient manner and is very advantageously, because the amount of complex of iridium can be significantly reduced.
