摘要

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. ... Recently, we have disclosed a novel regioselective Pd-catalyzed indolization from 2-chloroanilides tethered to internal alkynes,4 based on the previous protocol developed in this group.5 This unusual ...
