A highly chemoselective domino condensation/aza-Prinscyclization/retro-aldol between 2-alkenylanilines with β-dicarbonyl compounds under metal-free conditions was accomplished, giving a large category of valuable 2-substituted quinolines in good yields with excellent functional group toleration. This newly established process, adopting β-ketoesters as masked C1 synthons via C–C cleavage, could even
