Synthesis and biological evaluation of some novel quinazolinone derivatives

The benzodianine ring system, which result from the function of benzene ring with diazines constitute an important class of hetrocycles. Quinazoline is 1, 3-benzodiazine, which is essentially benzopyrimidine. Amongst the hetrocycles which have received considerable attention from chemists, the quinazolines have proved to be particular interest and importance. These compounds have been known since a long time and the first compound containing the quinazoline ring system was reported by Baeyer1.
