Synthesis , Reactions and Antimicrobial Activity on Some Novel Phthalazinone Derivatives

Abstract

 
ASIMPLE and efficient synthesis of [4-(3, 4-dimethylphenyl)-5, 6, 7, 8-tetrabromo-1-oxo-1H-phthalazin-2-yl]-acetic acid hydrazide (IV) has been carried out. The obtained hydrazide (IV) has been used in synthesis of some interesting heterocycles such as pyrazolone, thiazolidinone, pyrimidine, benzoxazine lactam, rhodanine, quinazoline and benzoxazinone (VIII
 
XVII). Some of the prepared compounds tested for in vitro antibacterial activities. Among those tested, many compounds showed good antibacterial activities.
