Regioselective Ir(<scp>iii</scp>)-catalyzed C–H alkynylation directed by 7-azaindoles

Abstract

Herein we report a novel iridium(iii)-catalyzed ortho-mono-alkynylation of 7-azaindoles under mild conditions. This approach provides a general and straightforward access to form novel 7-azaindole derivatives with ample substrate scope and broad group tolerance.
