Multi-substituted quinolines 3 were unexpectedly prepared from a cascadereaction of ortho-azido-β-nitro-styrenes with various carbonyl compounds. This method takes advantages of mild condition, simple work-up, high yield as well as wide substrate scope, which makes this method powerful for one-potsynthesis of multi-substituted quinolines.
