Asymmetric allylic oxidation reactions catalyzed by a chiral nonracemic and C₂-symmetric 2,2′-bipyridyl copper(<scp>i</scp>) complex

Abstract

The evaluation of a chiral, nonracemic and C2-symmetric 2,2'-bipyridyl ligand in copper(I)-catalyzed asymmetric allylic oxidation reactions of a series of cyclic alkenes with tert-butyl peroxybenzoate is reported (up to 91% ee, the highest reported enantioselectivity for a bipyridyl ligand copper(I) complex to date).
