Abstract

A gold-catalyzed C-H annulation of sulfilimines with N-phenylynamides affords 2-aminoindoles bearing a variety of substitution patterns in high selectivities. This reaction offers a facile approach to biologically important 2-aminoindoles by using inexpensive and readily available starting materials.
