  Achieving Chemo-, Regio-, and Stereoselectivity in Palladium-Catalyzed Reaction of γ-Borylated Allylic Acetates

  摘要：

  Three-carbon highly functionalized gamma-borylated allylic acetates underwent a regio- and stereocontrolled Tsuji-Trost reaction in the presence of palladium complexes. An Ipso substitution of the acetate with complete stereoretention of the chiral center was achieved, leading to vinylic boronates with enantiomeric excesses above 99%.
