Recent progress in transition-metal-catalyzed enantioselective indole functionalizations.

Numerous efficient synthetic methods for enantioselective indole functionalizations have emerged in recent years. This review summarizes the major achievements in the transition-metal-catalyzed enantioselective indole functionalization reactions since 2010 and focuses on C-C bond formation processes, including alkylations, arylations, cycloaddition reactions, and other reactions. It intends to give a compendious overview of the significant progress achieved in this area.
