reaction performed on an achiral allylicester using a chiral ligand-achiral nucleophile couple or a achiral ligand-chiral nucleophile couple, afforded optically enriched β-vinylcyclohexenyl amines. Thus, the hypothesis of a differentiation between two diastereotopic allylic sites of a π-allyl palladium complex by a nucleophile, confirm previous observations. nucleophilic substitutions - π-allyl palladium
