Ivanova, Olga A. published the artcileA Straightforward Approach to Tetrahydroindolo[3,2-b]carbazoles and 1-Indolyltetrahydrocarbazoles through [3+3] Cyclodimerization of Indole-Derived Cyclopropanes, Formula: C9H6FNO, the publication is Chemistry – A European Journal (2016), 22(4), 1223-1227, database is CAplus and MEDLINE.
A rapid new approach to produce biol. relevant bisindoles, namely indolyltetrahydrocarbazoles and indolo[3,2-b]carbazoles, was 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.
