One-pot synthesis of 1,2,4-oxadiazoles mediated by microwave irradiation under solvent-free condition

Microwave-assisted synthesis of 1,2,4-oxadiazoles of amidoximes under solvent free conditions was found to be an efficient method for one-pot synthesis of 1,2,4-oxadiazole derivatives from amidoximes and acyl chlorides. This method is an easy, rapid, and high-yielding reaction for the synthesis of 1,2,4-oxadiazoles.
