enantioselective one pot procedure for the synthesis of β-substituted amides was developed starting from the corresponding α,β-unsaturatedesters. This new methodology is based on the copper-catalysed enantioselective conjugateaddition of Grignardreagents to α,β-unsaturatedesters and subsequent direct formation of amides by quenching the corresponding enolates with different amines. Various primary
