Abstract
2-aryl-5-[5′-(4″-chlorophenyl)-2′-furyl]-1,3,4-oxadiazoles is synthesized by cyclization of 5-(4′-chlorophenyl)-2-furancarboxylic acid and aroyl hydrazines in the presence of phosphorus oxychloride under the condition of microwave irradiation.This synthetic strategy compared with traditional method has advantages of high yield, elevating reaction rate and simple work-up procedure.
