Abstract

The phosphorus-containing C2-symmetric chiral amine ligand (3) has been found to be highly effective for enantioselective allylic substitution catalyzed by palladium complex. A high level of enantioselectivity has been achieved in the reaction of racemic 1,3-diphenyl-2-propenyl acetate with various C-nucleophiles (>95% e.e.) and N-nucleophiles (84-92% e.e.).
