A Chiral Triazole Ligand for Enantiodivergent Catalysis in Asymmetric 1,4‐Addition of Arylboronic Acid

Abstract

Here, we reported a new type of chiral triazole‐oxazoline ligands for enantiodivergent catalysis. These ligands feature subtle modifications to the 1,2,3‐triazole skeleton and were systematically explored in the context of palladium‐catalyzed 1,4‐addition reactions of arylboronic acid to cyclic β‐substituted enones. The introduction of specific substituents on the triazole ligand led to switchable enantioselectivity, accompanied by consistently high yields.
