Abstract
Demonstrated herein is an unprecedented thioamide-directed cobalt (Co)-catalyzed umpolung annulation of sulfoximines enabled aryl thioamide with ynamide for the synthesis of highly substituted 2-amidoindenones. The cyclization is regioselective, making β-C-C and α-C-CO bonds. The transformation is even successful on a gram scale, exhibiting broad scope with labile functional group tolerance and constructing 43 unusual 2-amidoindenones of structural diversity. Control experiments and mechanistic investigation validate the regioselectivity outcome in this transformation.

Abstract
Ynamides are unique alkynes with a carbon-carbon triple bond directly attached to the nitrogen atom bearing an electron-withdrawing group. The alkyne is strongly polarized by the electron-donating nitrogen atom, but its high reactivity can be finely tempered by the electron-withdrawing group. Accordingly, ynamides are endowed with both nucleophilic and electrophilic properties and their chemistry has been an active research field. The catalytic intermolecular annulations of ynamides, featuring divergent assembly of structurally important amino-heterocycles in a regioselective manner, have gained much attention over the past decade. This review aims to provide a comprehensive summary of the advances achieved in this area involving transition metal and acid catalysis. Moreover, the intermolecular annulations of ynamide analogs including ynol ethers and thioalkynes are also discussed, which can provide insights into the reactivity difference caused by the heteroatoms.
