摘要: We report a series of cyclic analogues of 2,5-diamino-1,3,4-oxadiazoles which were prepared in a simple and general protocol. This method involves easy cyclisation of N-(aryl)-1,2-hydrazinedicarboxamides and mediated by tosylchloride/pyridine in ethanol (solvent) under a reflux condition (79–80 °C), over a time period of 20 h. We prepared different examples in a higher range of yields (80–98 %) by using this protocol.
