Synthesis, characterization and biological activity of new 3(4H)-quinazolinone derivatives

Quinazolinylbenzoic acid 1 was used as a precursor for synthesis of many heterocyclic systems. Ethyl 4-[4-oxo-2-phenylquinazolin-3(4H)-yl]benzoate 2 upon reaction with hydrazine hydrate gave 4-[4-oxo-2-phenylquinazolin-3(4H)-yl]benzoate benzoylhydrazide 3

Synthesis and antimicrobial activity of some pyrazoline derivatives of 4(3H)-quinazolinones

The present communication describes the synthesis and antimicrobial activity of some new 6,8-disubstituted-2-(phenyl/methyl)-3-|4-(3-methyl-5-pyrazolinon-1-yl)carbonyl) phenyl/benzyl/methyl|-4(3H)-qainazolinones.
