ABSTRACT
A number of novel 5-substituted-2-[[6-bromo-3,4-methylenedioxybenzyl]thio]-1,3,4-Oxadiazole derivatives [6a-l] have been synthesized to evaluate their antibacterial activity. Using aryl/aralkyl carboxylic acids [1a-l] as precursors, 5-substituted-1,3,4-Oxadiazol-2-thiols [4a-l] were yielded in good amounts.The derivatives, 4a-l, were subjected to electrophilic substitution reaction on stirring with 6-bromo-3,4-methylenedioxybenzyl chloride [5] in DMFto synthesize the required compounds. All the synthesized molecules were well characterized by IR, [1]H-NMR, [13]C-NMR and EIMS spectral data and evaluated for antibacterial activity against some bacterial strains of Gram-bacteria. The molecule, 6d, demonstrated the best activity among all the synthesized molecules exhibiting weak to moderate inhibition potential
