A C-2-symmetric chiral diamine ligand 1 was found to be effective for palladium catalyzed asymmetric allylic substitution of racemic 1,3-diphenyl-2-propenyl acetate 5 with dimethyl malonate. The X-ray analysis and NMR study of the palladium complex 7 with chiral diamine 1 have revealed the mechanism of high enantioselection.
