An intramolecular substitution of hydroperoxy-endoperoxide to a bis-endoperoxide.
[reaction: see text] A new and stereospecific synthesis for bis-endoperoxide has been developed starting from tetrahydronaphthalene. Photooxygenation of tetrahydronaphthalene resulted in the formation of hydroperoxy-endoperoxide. The bromination reaction of hydroperoxy-endoperoxide gave bis-endoperoxide, whose exact configuration has been determined by X-ray analysis. The lowest-energy conformer of bis-endoperoxide is the boat-chair form.
