The tricyclic azepino[1,2-a]indole acetates 7, readily accessible by visible-light-driven catalytic photooxygenation of cyclohepta[b]indoles 1, are convenient precursors to novel and uncommon cyclic C,N-diacyliminium ions 3. We report here the first

A short synthesis of the Kopsia alkaloid (±)-mersicarpine is enabled by the visible light-driven photooxygenation of a tetrahydrocarbazole, generating a perhydropyrido[1,2-a]indole dione as the immediate precursor to the natural product.

Tetrahydrocarbazoles and perhydrocyclohepta[b]indoles undergo a catalytic cascade singlet oxygenation in alkaline medium, which leads to chiral tricyclic perhydropyrido‐ and perhydroazepino[1,2‐a]indoles in a single operation. These photooxygenat
