  Ketene Dithioacetals in the Aza-Diels−Alder Reaction with N-Arylimines:  A Versatile Approach to Tetrahydroquinolines, 2,3-Dihydro-4-quinolones, and 4-Quinolones

  摘要：

  [GRAPHICS]The first successful use of ketene dithioacetals as dienophiles in the aza-Diels-Alder reaction with N-arylimines is described. Among the ketene dithioacetals tested, 1,4-benzodithlafulvenes are most effective in assembling the tetrahydroquinoline core. Subsequent chemical manipulations provide a concise and divergent approach to the synthesis of 2,3-tetrahydroquinolines, 2,3-dihydro-4-quinolones, and 4-quinolones.
