An efficient method for the synthesis of enaminones is described. The aldol-type addition of ketones to aromatic nitriles proceeded smoothly in the presence of a simple copper catalyst system (CuI–2,2′-bipyridine–NaOtBu) in N,N-dimethylformamide. Enaminones in satisfactory to excellent yields were produced using this technique.
