Preparation, Characterization and Biological Screening of Novel Imidazoles

The 4-benzylidene-2-(4-methoxyphenyl)oxazol-5(4H)-one (B) has been prepared from cyclo condensation reaction between hippuric acid (A) with p-anisaldehyde. A series of 4-benzylidene-1-(substitued-2-benzothiazolyl)-2-(4-methoxyphenyl)-1H-imidazol-5(4H)-one (D1-6) have been synthesized from 2-amino substituted benzothiazole (C1-6) by condensation reaction with 4-benzylidene-2-(4-methoxyphenyl) oxazol-5(4H)-one (B). The synthesized compounds were characterized by IR, 1H-NMR, 13C-NMR and Mass spectral data. All the compounds were screened for their antibacterial and antifungal activities.
