A route to aryl-substituted quinolines from N-tosyl 1-azadienes is described. The key steps are a [4+2] cycloaddition with benzyne followed by base treatment of the 1,4-dihydroquinoline product. The N-tosyl 1-azadienes were prepared from readily accessible cinnamaldehyde and chalcone substrates by condensation with p-TsNH2. Supplemental materials are available for this article.
