Palladium-catalyzed hydroalkylation of allylic amine derivatives by alkylzinc reagents is reported. This reductive cross-coupling reaction yields anti-Markovnikov products using a variety of allylic amine protecting groups. Preliminary mechanistic studies suggest that a reversible β-hydride elimination/hydride insertion process furnishes the primary Pd-alkyl intermediate, which then undergoes transmetalation
