Abstract:

Among five-membered aromatic heterocycles, 1,3,4- oxadiazoles are important class of aromatic heterocycles displaying a broad spectrum of biological activities, such as antimicrobial, anti-inflammatoy, analgesic, anticonvulsivant, anti-hypoglycemic. Compounds containing oxadiazole moieties have been described as possessing anticancer or muscle relaxant activity and have been used as fluorescent whiteners. Usually, the synthesis of non-symmetrical 2,5-disubstituted 1,3,4- oxadiazoles has mainly been done by dehydratation of diacylhydrazines or oxidative cyclization of aldehyde N-acylhydrazones, but many other reagents and reaction conditions have been reported to achieve their obtainment.
