A variety of symmetric and asymmetric 3,5-heterocyclic disubstituted 1,2,4-oxadiazole-4-oxides have been prepared through cycloaddition of aromatic and heteroaromatic nitrile oxides to heteroaromatic amidoximes. A library of novel, fully characterized, 1,

Iodobenzene diacetate in MeOH containing a catalytic amount of TFA efficiently oxidizes aldoximes to nitrile oxides. The latter may be trapped in situ with olefins in a bimolecular or an intramolecular mode. The new method enables the execution of tandem oxidative dearomatization of phenols/intramolecular nitrile oxide cycloaddition sequences leading to useful synthetic intermediates.
Unprecedented rearrangement reaction of nitrile oxides and a sterically congested 4-ylidene-5-isoxazolone

The reaction between nitrile oxides and 4-diphenylmethylene-3-phenylisoxazol-5-one (5) proceeds in an unprecedented fashion to yield 4-diphenylmethylene-2,3,3-trisubstituted derivatives (10). Their structure was determined by an X-Ray diffraction study.
