The synthesis of 2,3-ring-fused analogues of 7-fluoro-1-methyl-3-(methylsulfinyl)-4(1H)-quinolinone

The lithium enolate of cylic β-oxo sulfides has been shown to react with selected isatoic anhydrides to afford novel 9-oxothieno-, 10-oxothiopyrano- and 11-oxothiepino[3,2-b]quinolines. These cyclic sulfide compounds were then oxidized with 3-chloroperoxy
