The syntheses of some new derivatives of quinazoline and their annulated derivatives are described in this work. Investigation of antimicrobial activity of the new products was evaluated using agar well diffusion methods with determination of minimal inhibitory concentrations against six pathogenic bacteria and three pathogenic fungi. Most of the new compounds are potent as antimicrobialagents.

number of quinazolinone derivatives substituted at position‐3 are prepared from 3, 1‐benzoxazinone. Thus, treatment of 3, 1‐benzoxazinon with cyanoacetohydrazide or thionocarbohydrazide gave the quinazolinone derivatives. The quinazolinones have been utilized as synthon for new pyridinone, azete, thiazole, thiazolidinone, thosemicarbazide, and thiosemicarbazone derivatives. The structures of the synthesized
