Synthesis and some reactions of new 3, 1 nbenzosazine-4- one derivatives

ABSTRACT

2[2,5-Dimethylbenzoyl vinyl]-4H -3, j-benzoxazin-4 -one [II] can be obtained via reaction of B-[2,5-dimethylbenzoyl]-acrylyl chloride with anthranilic acid followed by cyclization of the anilide [I] formed by the action of Ac2O. The action of amines, hydrazines, hydroxylamine hydrochloride, urea and thioureas on the benzoxazone has been investigated
