Abstract
The Catalytic Asymmetric Vinylogous Mukaiyama (CAVM) reactions of various aldehydes with dienolate 1 using different enolate activations (CuF*(S)-TolBinap, t-BuOCu*(S)-Tol-Binap, and various chiral nonracemic ammonium fluorides derived from cinchona alkaloids) are described. These reactions proved to be highly regioselective leading exclusively to the alpha-aldol products in good yields and poor to good enantioselectivities.Entities:
