Synthesis of indoles via palladium-catalyzed C–H activation of N-aryl amides followed by coupling with alkynes
摘要:
A convenient and efficient method for the construction of indole skeleton was developed via Pd-catalyzed C-H activation of N-aryl amides and subsequent coupling with alkynes. Both stoichiometric and catalytic versions have been successfully achieved. (C) 2011 Elsevier Ltd. All rights reserved.

A simple and efficient approach for the preparation of substituted indoles and isoquinolones via a nickel-catalyzed Larock-type heteroannulation reaction is reported. This transformation employed air-stable and inexpensive Ni(dppp)Cl2 as a precatalyst and Et3N as a mild base. Moreover, the reaction occurs efficiently under mild conditions, and a wide range of substituted indoles and isoquinolones bearing
