A RhIII‐catalyzed intramolecular redox‐neutral atom‐economic annulation of a tethered alkyne has been developed to efficiently construct 2‐amidealkyl indoles with completely reversed regioselectivity by a CHactivation pathway. Furthermore, using the RhIII‐catalyzedCHactivation/annulation as a key step, a one‐pot synthesis of pyrido[1,2‐a]indoles has also been developed and applied to a highly

A robust one-pot process has been developed for the synthesis of a variety of polycyclic indole skeletons via a consecutive sequence of hydroamidation and palladium-catalyzed annulation, from inexpensive 2-chloroanilines bearing tethered acetylenes.
