ChemInform Abstract: Synthesis of Some Oxadiazole Derivatives.

Abstract

175ChemInform Abstract The oxadiazoles (VI) are synthesized from the hydrazides (III) by phosphorus oxychloride-induced cyclization and subsequent reaction with the sulfonamides (V).

Antimicrobial activity of amino acid, imidazole, and sulfonamide derivatives of pyrazolo[3,4‐d]pyrimidine

“…They are associated with antibacterial [16], antifungal [17], antitumor [18], and antiinflammatory [19] properties. Condensation of 1 with some sulfonamides in N,N-dimethylformamide (DMF) gave only the sulfonamide derivatives 12-16, whereas, conducting this reaction in presence of anhydrous K 2 CO 3 [20] …”
