Synthesis of New Heterocycles: Condensation of 2-Methyl-4H-naphth[1,2-d][1,3]oxazin-4-one with Schiff Bases and Formation of 3-Aryl-2-styrylbenzo[h]quinazolin-4(3H)-ones

Abstract Condensation of 2-Methyl-4H-naphth[1,2-d][1,3]oxazin-4-one (2) with Schiff bases (3) in acetic acid has resulted in 3-aryl-2-styrylbenzo[h]quinazolin-4(3H)-ones (4), characterized by spectral and analytical methods.
