With hypocrellin A associated high pressure sodium lamp sensitized photooxygenation of cis,cis-1,5-cyclooctadiene in methanol gave cis-5,8-dihydroperoxyl-1,3-cyclooctadiene efficiently and stereoselectively. It is shown that cis-5,8-dihydroxy-1,3-cyclooctadiene is thermally rearranged to 6-hydroxy-4-cyclooctenone instead of 6-hydroxy-3-cyclooctenone. The thermal rearrangement process was discussed.
