## Abstract Chiral spiro diphosphines (SDP) are efficient ligands for the Pd‐catalyzed asymmetric allylic alkylation of 1,3‐diphenyl‐2‐propenyl acetate with dimethyl malonate and related nucleophiles. The newly synthesized ligand DMM‐SDP (**1e**) with 3,5‐dimethyl‐4‐methoxy groups on the __P__‐phen
