Acyl(arylcarbamoyl)ketene dithioacetals 2 and acyl(1-alkenylcarbamoyl)ketene dithioacetals 5 obtained from the corresponding ß-oxo amides 1, 4 were thermally cyclized to give various 3-acyl-4-alkylthio-2(1H)-quinolinones 3, and 3-acyl-4-alkylthio-5-aryl-2(1H)-pyridones 6, respectively, depending on the substituent of the amide group.
