摘要：

The reaction of N1-acyl-2-ethoxycarbonylacetamidrazones 1 with diethyl ethoxymethylenemalonate (EMME) is reported. By refluxing equimolecular amounts of 1 and EMME in DMSO/toluene (or ethanol) solution, the 1-acylamino-2(1H)-pyridones 2 were obtained in good yield. When the reaction was performed in ethanolic solution in the presence of triethylamine, the 6-acylhydrazino-2(1H)-pyridones 3 were obtained.
