Transition Metal-Catalyzed C-H Activation of Indoles

The last decades have seen a tremendous expanse in the application of C-H activation of many different substrate classes, including the invaluable indole scaffold. Following the exciting emergence of C-H activation as a multi-faceted platform for functionalization, a versatile tool box has been developed for the preparation of structurally diverse indoles. This review article discusses recent advances and strategies for transition metal-catalyzed C-H activation of indoles.
