A palladium complex of newly designed chiral 2-(phosphinoaryl)pyridine (4b) was found to be an effective catalyst for asymmetric allylic alkylation. High enantioselectivity was achieved in the reactions of both 1,3-diphenyl-2-propen-1-yl acetate (98% ee) and (2E)-1-methyl-2-butenyl phenyl carbonate (93% ee) with dimethyl malonate.
