1,3,4-Oxadiazole derivatives are a class of important bioactive molecules, showing good antibacterial, anti-inflam- matory and anticancer activities. In the present study, an efficient one-pot synthetic methodology has been developed for the construction of 1,3,4-oxadiazoles by utilizing acylhydrazine and alkylamide as reactants in the absence of alkaline or metallic catalysts. The expected 1,3,4-oxadiazole derivatives can be obtained with a maximum 85% yield for 10 h. This method has the advantages of simple operation, mild conditions, few by-products and wide range of substrates. And it can achieve gram preparation, showing good practical value. The mechanism study showed that the tautomerism of amide electron cloud, and the activity of tetrabutylammonium iodide (TBAI) and hydrazide carbonyl group played an important role in the reaction.
