Process for the preparation of chiral 1,2-diol derivatives from chiral epoxides by using chiral salen catalyst

摘要

The present invention relates to a process for the preparation of chiral 1,2-diol derivatives from chiral epoxide, and more particularly, even if the re-use without further catalyst after the regeneration step has unique molecular composition used for the reaction to maintain the same catalytic activity because the catalyst regeneration repeating without processing by reusing the effectively produced by using a chiral salen catalyst having a chiral drug or the possible advantage of a chiral 1,2-diol derivative of high optical purity which can be used as a raw material for the production of food additives and the like from the chiral epoxide It relates to a method.
