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.

[reaction: see text] A one-step method was developed for elaboration of a variety of polycyclic indole skeletons via a novel palladium-catalyzed intramolecular indolization of 2-chloroanilines bearing tethered acetylenes. This novel intramolecular indolization method unveils an unusual syn amidopalladation pathway of a tethered alkyne.
