A rapid and efficient method for the preparation of various poly-substituted quinolines has been developed through the Friedlander condensation of 2-aminoarylketone or 2-aminoarylaldehyde with carbonyl compounds in the presence of p-toluene sulphonic acid, which was achieved by both microwaveirradiation and conventional heating under solvent-free conditions.
