A new double-activation catalysis is presented for the Morita-Baylis-Hillman (MBH) reaction of an alpha,beta-unsaturated ketone and an aldehyde by the combined use of a heterobimetallic asymmetric complex and tributylphosphine ((n-Bu)(3)P) to afford the alpha-methylene-beta-hydroxy ketone with up to 99% ce.
