The present invention relates to new chiral salen catalysts and the preparation method of chiral compounds from racemic epoxides using the same. More specifically, it relates to new chiral salen catalysts that have high catalytic activity due to new molecular structures and have no or little racemization of the generated target chiral compounds even after the reaction is completed and can be also reused without catalyst regeneration treatment, and its economical preparation method to mass manufacture chiral compounds of high optical purity, which can be used as raw materials for chiral food additives, chiral drugs, or chiral crop protection agents, etc., using the new chiral salen catalysts.
本发明涉及新的手性Salen催化剂及其利用该催化剂从外消旋
环氧化物制备手性化合物的制备方法。更具体地说,本发明涉及新的手性Salen催化剂,由于其新的分子结构具有高催化活性,并且即使在反应完成后也没有或很少有产生目标手性化合物的消旋化,并且可以在不进行催化剂再生处理的情况下重复使用,以及其经济的制备方法,以大规模制造高光学纯度的手性化合物,这些化合物可以用作手性
食品添加剂、手性药物或手性作物保护剂等的原材料,利用新的手性Salen催化剂。
