  Diastereoselective Room-Temperature Pd-Catalyzed α-Arylation and Vinylation of Arylmandelic Acid Derivatives

  摘要：

  Palladium-catalyzed alpha-arylation and vinylation of dioxolane (S,S)-I, easily obtained from (S)-mandelic acid, proceeds with high yields and excellent diastereoselectivity at room temperature employing commercially available P(t-Bu)(3)center dot HBF4 and Pd(OAc)(2) as a catalytic precursor system. This method displays general utility for a large variety of aryl, heteroaryl, and vinyl bromides.
