Abstract
Catalytic allylation of imines with allyltributylstannane and catalytic Mannich-type reactions of imines with silyl enol ethers were successfully carried out in the presence of a group 4 metal triflate, such as Zr(OTf)4 or Hf(OTf)4, to afford the corresponding adducts in high yields.Keywords
