Synthesis and Spectral Study of Novel Benzopyrone and Quinolinone Derivatives

A series of novel benzopyrones and quinolinone derivatives were prepared using the readily obtainable 6-nitro-benzo-2-pyron-3-carboxylate through the reaction with nitrogen nucleophilic reagents such as cyclohexyl amine, p-aminoacetophenone, diamines, hydrazine hydrate, thiosemicarbazide, anthranilic acid and carbon nucleophile as malononitrile. The IR, 1H NMR and mass spectra of the new synthesised compounds were discussed.
