An efficient synthesis of polycyclic indole and pyrrole derivatives via a ruthenium-catalyzed intramolecular allylic dearomatization/migration reaction has been developed. This method features wide substrate scope, mild reaction conditions, and an operationally simple procedure. The capture of the spiro intermediate provides solid evidence for the dearomatization/migration reaction pathway.

Herein we report a highly enantioselective synthesis of polycyclic indoles and pyrroles with up to 99% ee by an iridium catalyst system consisting of a commercially available iridium precursor and a readily accessible ligand. Investigation of the reaction mechanism led to the discovery of an unprecedented dearomatized spiro intermediate and its in situ migration phenomenon. The new reaction mode features switching of the substituent from the indole C-3 position to the C-2 position (from the C-2 position to the C-3 position in the case of pyrrole) without loss of the enantiomeric purity, providing a novel concept in designing the asymmetric construction of enantiopure polycyclic indoles and pyrroles.
