A convenient and efficient method was developed for the synthesis of quinolines, an important class of potentially bioactive compounds. The quinoline derivatives were prepared in water, an excellent solvent in terms of environmental impact and with reduced waste production. PEG-SO3H effectively catalysed the one-pot synthesis of quinolines by the condensation of o-aminoaryl ketones and carbonyl compound with high yields (75–95%). The compounds were isolated by simple filtration in a high purity form.

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.
A series of 2,4-disubstituted quinolines were easily prepared through a one-pot reaction of structurally diverse 2-aminoaryl ketones with various arylacetylenes in the presence of K5CoW12O40Ë3H2O as a reusable and environmentally benign catalyst under microwave irradiation and solvent-free conditions.

AbstractAn efficient, useful and general procedure for the synthesis of 2,4-disubstituted quinolines via one-pot three-component reaction of aryl amines, aryl aldehydes and phenylacetylene using Al2O3 nanoparticles/methanesulfonicacid (nano-AMA) as a new catalyst has been described. The major advantages of this protocol are high yields, inexpensive catalyst, short reaction times, green and reusable
