A series of six 4-aryl Benzelidene-2-phenyl-5- oxazolone derivatives were synthesized by condensation of aromatic aldehydes with N-benzoyl glycine (Hippuric acid) in the presence of sodium acetate and acetic anhydride at room temperature in ethanol. Six of the compounds are new derivatives. The structures of the compounds were evaluated based on 1H-NMR , IR and FTIR methods and by elemental analysis. .All the derivative compounds prepared were tested for their antimicrobial activity by disk diffusion technique. Test organisms: Bacteria like Staphylococcus aureusMTCC 7443 and Salmonella typhimuriumMTCC 733 Fungi like C.albicans and A.flavus The results were compared with those of the standard 0.5% Ciprofloxacin. The derivatives with Salicylaldehyde and cinnamaldehyde were showed excellent activities against E. coli. and Staphylococcus aureusMTCC 7443 : than Salmonella typhimuriumMTCC 733 bacteria. It also showed reasonable activity withFungi like C.albicans than A.flavus
