Reaction of Isatoic Anhydride With Bifunctional Reagents: Synthesis of Some New Quinazolone Fused Heterocycles, 2-Substituted Anilinoheterocyclic Derivatives and Other Related Compounds

A new synthesis of quinazolone fused heterocycles (2, 5, 8), anilinoheterocycles (4, 7, 10, 12, 14) and substituted 2-aminoquinoline (15, 16) based on the reaction of isatoic anhydride (1) with different active bifunctional compounds in presence of glacial acetic acid and freshly fused sodium acetate is described. Structures of the newly prepared compounds are established by chemical and spectral data.
