A series of 1-aryl-1,2-dihydrobenzo[f]quinolin-3(4H)one derivatives were synthesized by one-pot muticomponent reaction of Meldrums acid with benzaldehyde, naphthalene-2-amine in glycerol. Glycerol, a new green organic solvent, it not only acts as a catalyst but also as a recyclable solvent by significantly enhancing the intramolecular cyclization. When compared with classical methods, this method has the advantages of milder reaction conditions, good yields, easy processing and environmental benignity. All compounds were characterized by elemental analysis, FT-IR and 1H NMR spectra.
