A one-pot method was developed for the preparation of 3,5-disubstituted 1,2,4-oxadiazoles containing an alkenyl fragment I (R = Ph, 3-O2NC6H4, 3-pyridyl, etc.; R1 = Ph, 3-ClC6H4, 2-thienyl, etc.), which entails the preparation of O-acylamidoximes and their subsequent cyclization using N,N¡ä-dimethylacetamide as a solvent. The proposed method allows to significantly reduce the overall synthesis time by carrying out all steps sequentially in a single reactor, avoiding the step of isolation of the intermediate O-acylamidoxime, leading to the production of 5-alkenyl-1,2,4-oxadiazoles in high yields.
