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