Aryl nitrile oxides undergo 1,3-dipolar cycloaddition with alkanone hydrazones to give 4-amino-3-aryl-5,5-dialkyl-δ2-1,2,4-oxadiazolines. Lead tetraacetate oxidation of these 4-amino-δ2-1,2,4-oxadiazolines brings about smooth heteroring cracking into the corresponding nitrile, ketone, and nitrogen.
