【 摘 要 】

The reaction of aryl nitriles with hydroxylamine using acetic acid as a catalyst followed by subsequent addition of crotonoyl chloride to the intermediate amidoxime represents a straightforward one-pot access to new 1,2,4-oxadiazole synthesis under mild conditions. The course of the reaction was found to be high yielding and all new compounds were well characterized by nuclear magnetic resonance (NMR), mass spectrometry (MS) and elemental analysis.
