Diastereoselectivity Switch in Cooperatively Catalyzed Three-Component Reactions of an Aryldiazoacetate, an Alcohol, and a β,γ-Unsaturated α-Keto Ester

Abstract

A highly switchable,diastereoselectivity-controlled, three-component reaction of aryldiazoacetate, alcohol,and β,γ-unsaturated α-keto esters has been achieved through a dual-metal cooperative catalysis strategy.
