Thermolytic ring closure reactions of 4-azido-3-phenylsulfanyl- and 4-azido-3-phenylsulfonyl-2-quinolones to 12H-quinolino-[3,4-b][1,4]benzothiazin-6(5H)-ones [1]

4-Hydroxy-3-phenylsulfanyl-2-quinolones 2 and 4-hydroxy-3-sulfonyl-2-quinolones 7, which are readily accessible from 4-hydroxy-2-quinolones 1 and diphenyldisulfide or thiophenol, can be converted to 4-azido-3-phenylsulfanyl-2-quinolones 10 or 4-azido-3-ph

Anions of heteroaromatic 1,3-dicarbonyl compounds, such as 4-hydoxy-2-quinolones and 4-hydroxy-coumarins, react in DMF in the presence of potassium carbonate with diaryl disulfides to yield 3-arylsulfenyl derivatives. The arylthiolate anions formed in thi

Anti-allergic 4-hydroxy-3-sulfinyl-quinolin-2(1H)-ones are prepared by reacting an isatoic anhydride with the carbanion resulting from the treatment of sulfinyl acetic acid alkyl esters with a proton abstracting agent.
