Abstract

In the present study, some oxadiazole derivatives have been synthesized by incorporating azetidinyl and thiazolidinyl moieties at its 2-position such as 5-(p-methoxyphenyl)-[2-substitutedbenzylidenylimino]1,3,4- oxadiazole 2-6, 5-(p-methoxyphenyl)-[2-(3´-chloro-2´-oxo-4´-substitutedaryl-1-azetidinyl)1,3,4-oxadiazole 7-11 and 5-(p-methoxyphenyl)-[2-(2´-substitutedaryl-4´-oxo-1´,3´-thiazolidin-3´-yl)1,3,4-oxadiazole 12-16. The structure of these compounds have been elucidated by elemental analysis (C, H, N) and IR, 1H-NMR, Mass spectroscopic techniques. Further, these compounds were subjected to screening for antibacterial activities against different bacterial strains.
