Abstract

A gold-catalyzed intermolecular ynamide amination-initiated aza-Nazarov cyclization enables a facile and efficient synthesis of various 2-aminopyrroles in good yields. High flexibility, broad substrate scope, and mild nature of this reaction render it a viable alternative for the construction of 2-aminopyrroles.
