Saturated fulvene endoperoxides give highly oxygenated compounds upon thermolysis in the presence of acetic acid. Depending on whether the fulvene precursor is 6-mono or 6,6-disubstituted, one obtains either lactol acetates or 1,5-carbonyl compounds, respectively.

The saturated endoperoxide derived from 6,6-dimethylfulvene was shown to be a unique source of an allene oxide and a cyclopropanone: inter- and intramolecular trapping experiments provided permissive evidence that such intermediates are indeed operative in the thermal isomerizations of fulvene endoperoxides.
