Abstract: A simple, efficient, and general multicomponent reaction involving an enolizable ketone, a primary amine, and an N-protected 3-nitroindole was developed for the synthesis of a range of functionalized pyrrolo [3,2-b]indoles. The methodology was efficaciously utilized for the “pyrroloindoliztion” of natural products, the pyrrolization of 3-nitrobenzo-[b] thiophene, and the gram-scale synthesis of pyrroloindole. Furthermore, a “one-pot” approach for accessing indolo [3,2-b] indoles was realized.
