Three-component reactions of nitroarenes, aldehydes, and phenylacetylene in the presence of indium in dilute hydrochloric acid produce the corresponding quinoline derivatives under reflux. The conversion in this one-potsynthesis involves the following steps: (i) reduction of the nitroarenes to anilines, (ii) coupling of the anilines, aldehydes, and phenylacetylene, (iii) cyclization of the resulting

A new general synthesis of quinolines was developed from ketoximes and alkynes in the presence of Tf2O. It offered the first direct synthesis of quinolines by using the nitrilium salts generated in situ from a Tf2O‐promoted Beckmann rearrangement of ketoximes under very easy conditions.

A simple and green route towards disubstituted quinolines via A(3)-coupling using 1 mol% FeCl3 is described. Using this approach, the above-mentioned derivatives were synthesized in moderate to good yields (45-95%) under solvent-free, microwave conditions. Preliminary investigations have indicated that a further decrease in catalyst amount is possible with a satisfactory yield still observed.
