H activations thereby offering an access to functionalized heterocycles including the indoles. The metal‐catalyzed transformations proceeding the CH functionalizations of C4, C5, C6, and C7 position will be covered in the article along with applications to analogs systems in tetrahydroquinolines and tetrahydroisoquinolines.
