We disclose a gold-catalyzed conversion of unactivated β-ketopropargyl amines to polysubstituted pyrroles under mild, operationally simple conditions. A broad substituent survey reveals clear structure-reactivity trends. With application of the revealed protocol, leveraging the propargyl tolerance, combining AuCI3 with TBACN telescopes the sequence to a bicyclic indolizine ring.
