A highly chemoselective domino condensation/aza-Prins cyclization/retro-aldol between 2-alkenylanilines and β-dicarbonyl compounds provides a large variety of valuable 2-substituted quinolines in good yields. This metal-free reaction tolerates a broad range of functional groups and can even be simpliefied into a three component domino reaction.
