Catalytic asym. Mukaiyama-type aldol reaction using MeO3Si enol ethers was achieved using 2,2′-bis(di-p-tolylphosphino)-1,1′-binaphthyl (p-Tol-BINAP)·AgF complex as a catalyst. The chiral Ag(I) catalyst was easily generated by mixing p-Tol-BINAP and AgF in MeOH at room temperature High syn- and enantioselectivities were obtained from both the E- and Z-silyl enol ethers. Use of a 1:1 mixture of MeOH and acetone as a solvent in the reaction of cyclohexanone-derived MeO3Si enol ethers resulted in higher enantioselectivity.
