title: A Straightforward Approach to Tetrahydroindolo[3,2-b]carbazoles and 1-Indolyltetrahydrocarbazoles through [3+3] Cyclodimerization of Indole-Derived Cyclopropanes.
abstract: A rapid new approach to produce biologically relevant bisindoles, namely indolyltetrahydrocarbazoles and indolo[3,2-b]carbazoles, has been developed, based on the Ga(OTf)3 -catalyzed [3+3] cyclodimerization of indole-derived donor-acceptor cyclopropanes. Chemoselectivity of the process depends on the location of the three-membered ring at the indole core.
