An efficient and mild one-pot protocol has been developed for the synthesis of 1,2,4-oxadiazoles via the reaction of amidoximes with dicarboxylic acid anhydrides in a NaOH/DMSO medium. The method allows the synthesis of diversely substituted carboxylic acids bearing the 1,2,4-oxadiazole motif, – a popular building block for pharmaceutical research, in moderate to excellent yields. The reaction scope includes aromatic and heteroaromatic amidoximes as well as five-, six- and seven-membered anhydrides. The advantages of this procedure are proven gram-scalability and the use of inexpensive starting materials, which from a process chemistry point of view are essential for future industrial applications.

(Chemical Equation Presented) In this study, a novel series of substituted 4,6-difluoro-2-{2-[3-(substituted-phenyl)-[1,2,4]-oxadiazol-5-yl]-ethyl} -1H-benzo[d]imidazole derivatives were synthesized by condensation of 2,4-difluoro-6-nitrophenyl amine with 3-(substitutedphenyl-[1,2,4]-oxadiazol- 5yl) propionic acid by using 2,4,6-trichlorobenzoyl chloride in the presence of triethyl amine base. The compounds were evaluated for their preliminary in vitro antibacterial activity against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Salmonella typhosa. The antibacterial data of the tested compounds indicated that most of the synthesized compounds showed moderate activity with reference standard Gentamycin.
