Palladium catalysis enables an unprecedented, highly effective synthesis of γ-lactones from homoallylic alcohols in one step. The protocol affords aryl, alkyl, and spiro γ-lactones directly from readily available homoallylic alcohols in good yields with excellent functional group tolerance and high chemoselectivity under mild conditions.
