Chiral polymeric salen catalyst, and a process for preparing chiral compounds from racemic epoxides by using them

摘要

The present invention relates to chiral salen catalysts and a process for preparing chiral compounds from racemic epoxides by using them. More particularly, the present invention is to provide a chiral polymeric salen catalyst and its use for producing chiral compounds such as chiral epoxides and chiral 1,2-diols economically in high yield and high optical purity by performing stereoselective hydrolysis or racemic epoxides.
