Abstract: The light-mediated catalytic singlet oxygenation of the hexahydrocyclohepta[b]indole has been studied. After optimization, the reaction mechanism was isolated and investigated. Additional recording of time-turnover profiles enabled postulation of the reaction mechanism. Next, various derivatives were converted to the corresponding hemiaminals. Finally, the cascade photooxygenation was integrated into the natural product synthesis of mersicarpine and two functionalized carbazole derivatives were converted into mersicarpine analogues.
