Highly Efficient Copper(I) Iodide‐Tolyl‐BINAP‐Catalyzed Asymmetric Conjugate Addition of Methylmagnesium Bromide to α,β‐Unsaturated Esters

Abstract

Abstract A highly efficient asymmetric conjugate addition of methylmagnesium bromide (MeMgBr) to α,β‐unsaturated esters catalyzed by copper(I) iodide‐tolyl‐BNIP (CuI‐Tol‐BINAP) is described.
