The lithium enolate of cyclic ß-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-chloroperoxybenzoic acid to afford either the corresponding 1-oxides or 1,1-dioxides.
