Gold-catalyzed cascade cyclization of <i>N</i>-propargyl ynamides: rapid access to functionalized indeno[1,2-<i>c</i>]pyrroles

Abstract

A new gold-catalyzed cascade cyclization of <italic>N</italic>-propargyl ynamides involving a presumable vinyl cation intermediate has been developed, allowing the efficient and practical synthesis of various functionalized indeno[1,2-<italic>c</italic>]pyrroles.
