(Chemical Equation Presented) A rare example of the umpolung of an enolate forms the basis of the title reaction. In this procedure, a Grignard reagent is added to the iminium ion formed from the Weinreb amide upon treatment with a base (see scheme). When a chiral amide was used as the starting material, the nucleophilic addition proceeded with high diastereoselectivity. LDA = lithium diisopropylamide.
