1,3‐Difunctionalization of Imino‐Carbenes via Rhodium‐Catalyzed Reactions of Triazoles with Acyl Selenides

Abstract

Herein, we report on the rhodium‐catalyzed reaction of triazoles with acyl selenides. Under thermal reaction conditions and in the presence of a rhodium catalyst, a rapid 1,3‐difunctionalization reaction occurs to provide valuable α‐seleno enamides with high stereoselectivity and broad functional group tolerance, which was demonstrated in 35 examples with up to 95% yield. Computational calculations suggest a reaction pathway that gives a direct access to the 1,3‐difunctionalization without intermittent formation of ylide intermediates.
