Thermal cyclization of ketene dithioacetals: A convenient synthetic route to substituted 2(1H)-quinolinones and 2(1H)-pyridones

Pak,Choi

, p. 1291 - 1294 (2007/10/02)

Acyl(arylcarbamoyl)ketene dithioacetals 2 and acyl(1-alkenylcarbamoyl)ketene dithioacetals 5 obtained from the corresponding β-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(
