Vinyl azetidines can be converted to nitro olefins , or to unsaturated aldoximes –, which are useful precursors for intramolecular nitrile oxide - olefincycloadditions (INOC). Such INOC reactions proceed with a fair degree of stereoselectivity producing novel heterocycles.

Allylamines possessing a properly positioned aldoxime or ketoxime chain undergo thermally induced dipolar cycloaddition to bicylic isoxazolidines, with stereospecific introduction of three stereo centers. This provides an entry into stereospecifically functionalized pyrrolidines.
