copper-mediated cross-coupling of aminoacid derived beta-amido-alkylzinc iodides 1 and 3 with a range of acidchlorides. The present method uses CuCN.2LiCl as the copper source and for organozinc reagent 1 the methodology appears to be limited to reaction with more stable acidchlorides, providing the desired products in moderate yields. When applied to organozinc reagent 3, however, the protocol is more
