Picture perfect: By using the reagent trimethylaluminium and β,γ-unsaturated α-ketoamides, 1,4-adducts were obtained with perfect 1,4-regioselectivity and good to excellent yields and ee values. The potential synthetic utility of the methodology was highlighted by preparation of γ-methyl-substituted carbonyls, key synthons to many natural products. binap=2,2′-bis(diphenylphosphino)-1,1′-binaphthyl, TC=thiophene carboxylate.
