A one-pot tandem P-Michael addition/SN2/intramolecular Wittig Reaction of in situ generated aza-o-quinone methides with PPh3 and α-bromo ketones has been reported. This protocol provided an efficient and mild approach to synthesize 2,3-disubstituted dihydroquinolines in 25%~93% yields. In addition, the 2,3-disubstituted quinolines could also be obtained by simply modification of the reaction conditions.

Key words: aza-o-quinone methides, dihydroquinoline derivatives, quinoline derivatives
