Regioselective Ir(iii)-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.
