A novel one-pot three-component regioselective synthesis of highly substituted pyridin-2-one derivatives starting from simple and readily available starting materials is described. The reactive zwitterionic intermediate generated by the addition of an isocyanide to dimethyl acetylenedicarboxylate (DMAD) was trapped with N-arylidene-2-cyanoacetohydrazides to afford the title compounds in moderate to
