The synthesis of poly-functional moieties as one unit has been under consideration by the synthetic chemists to search out new potent molecules. 2-Chlorobenzoic acid (1) was converted to 5-(2-chlorophenyl)-1,3,4-Oxadiazol-2-thiol (4) through a series of steps. This nucleophile was attached with different electrophiles, prepared by the reaction of aryl/alkyl amines with 2-bromoacetylbromide, in NaH/DMF to synthesize N-substituted-2-((5-(2-chlorophenyl)-1,3,4-Oxadiazol-2-yl)sulfanyl)acetamide, 7a-f. The molecule 4 was stepped to ethyl ester and carbohydrazide. The carbohydrazide was made to react with aryl carboxaldehydes in methanol to synthesize N'-substituted-2-(5-(2-chlorophenyl)-1,3,4-Oxadiazol-2-ylthio)acetohydrazide, 11a-i. The structures of all the molecules were corroborated through IR, ¹H-NMR and EI-MS spectral data. Both the series were screened for antibacterial and enzyme inhibition activity.
