microwave-assisted synthesis of substituted quinolines is described. The quinolines were synthesized by a multicomponent domino reaction of anilines, aldehydes and terminal aryl alkynes. The synthetic pathway involves the formation of an imine, followed by the intermolecular addition of an alkyne to the imine. This intermediate immediately undergoes ring closure and oxidative aromatization. The reaction is catalyzed

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.
