Abstract

A simple and efficient method for the synthesis of chiral biphenylbisoxazoline ligands was developed. The bishydroxylamide precursors of ligands showed a dynamic atropselective resolution effect in the crystallization process. When biphenylbisoxazoline ligands were coordinated to tetrakis (acetonitrile) copper (I) hexafluorophosphate, it resulted in the formation of only a single diastereomer complex (S, aS, S), which behaved as a catalyst ...
