摘要
Several derivatives of 2H-phenyl[f]chromene-2-carbonitrile, 2H-benzo[f]chromano[2,3,4:d, e]pyrido[2,3-d]pyrimidine, and benzo[g]-2-quinolone were prepared by the direct condensation of malononitrile with 2-hydroxy-1-naphthaldehyde in the presence of various ketones and ammonium acetate. The effect of solvent, ratio of reactant, and different basic catalysts were studied.
