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
