α-(N-Carbamoyl)alkylcuprates (RCuCNLi or R2CuLi) react with allylic phosphates to afford homoallylic amines in good chemical yields. Regioselectivity is governed by steric factors in both the cuprate reagent and phosphate substrate and systems can be designed to give either the S N2′ or SN2 substitution product cleanly. Excellent enantioselectivities can be achieved with either a scalemic α-di[(N- carbamoyl)-alkyl]cuprate and an achiral phosphate or with a scalemic allylic phosphate and an achiral cuprate reagent.
