A new convenient, efficient and environmentally eco-friendly protocol for Friedländer synthesis of polysubstituted quinolines and naphthyridines is described. A wide variety of new products were readily prepared in the presence of propylphosphonic anhydride (T3P®) in short reaction times and excellent yields under mild conditions.

An efficient and eco-friendly synthetic route for Friedländer quinoline synthesis of polysubstituted quinolines is described. This green chemical method starts from various 2-aminobenzophenones and mono- or dicarbonyl synthons and uses reusable Nafion NR50 material as a solid catalyst in ethanol undermicrowaveirradiation. The protocol has a high generality of functional groups and provides the desired
