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.
由 1-芳基-2-溴烷酮和锌生成的烯醇酸锌与 2-(1-芳基亚甲基)丙二酸二甲酯反应生成 2-(2-烷基-1,3-二基-3-氧代丙基)丙二酸二甲酯。后者与苄胺或环己胺反应生成相应的二取代酰胺,而与哌啶、吗啉和对甲氧基苯胺反应则生成相应目标衍生物的单取代酰胺。
