The two-step nitrone or nitrile oxide cycloaddition–rearrangement thermal process applied to bicyclopropylidene gives 4-pyridone, 7-indolizinone, and 2-quinolizinone derivatives containing a spirocyclopropane linkage α to a carbonyl group.

Two members of a new class of heterocyclic ketones with alpha- spirocyclopropane groups, obtained by 1,3-dipolar cycloaddition to bicyclopropylidene and thermal rearrangement of the adducts, have shown moderate DNA cleaving activity on a pUC19 DNA plasmid. These compounds have structural analogies with the potent carcinogenic sesquiterpenes Ptaquiloside and Illudin.
