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.

1,3-Dipolar cycloaddition of N-benzyl-C-(methoxycarbonyl)-nitrone (3a), N-benzyl-C-phenylnitrone (3b), N-benzyl-C-cyanonitrone (3c), N-(p-methoxybenzyl)-C-cyanonitrone (3d), N-phenyl- (3e) and N-(2-pyridyl)-C- methylnitrones (3f) to bicyclopropylidene (2)
Thermal rearrangement of nitrone and nitrile oxide cycloadducts to bicyclopropylidene. Synthesis of 3-spirocyclopropane-4-pyridone and furo[2,3-c]pyridine derivatives

Bicyclopropylidene smoothly undergoes 1,3-dipolar cycloadditions to nitrones or nitrile oxides under different reaction conditions. The strained bisspirocyclopropanated isoxazolidines obtained from nitrones easily rearrange upon heating with selective ope
