Zinc enolates generated from 1-aryl-2-bromoalkanones and zinc react with dimethyl 2-(1-arylmethylene)malonate to form dimethyl 2-(2-alkyl-1,3-diaryl-3-oxopropyl)malonates. The latter react with benzylamine or cyclohexylamine to form the corresponding disubstituted amides, while the reactions with piperidine, morpholine, and p-methoxyaniline provide monosubstituted amides of the corresponding target derivatives.
