Quinolines from Morita-Baylis-Hillman acetates of 2-azidobenzaldehydes

A simple method for synthesizing several 2-alkoxy-3-arylsulfinylmethylquinolines using an aza-Wittig type reaction of 3-(2-azidophenyl)-2-(arylsulfinylmethyl)propenoates, which were readily obtained from the Morita-Baylis-Hillman acetates of 2-azidobenzaldehydes, has been developed.
