Article Abstract
A new, one-step rhodium(III)-catalyzed annulation of 4-arylbut-3-yn-1-amines with internal alkynes through C-H functionalization is reported. This reaction allows the formation of three new chemical bonds, including two C-C bonds and one C-N band, thus selectively assembling various spiro[indene-1,2'-pyrrolidine]s with excellent functional group compatibility, high atom-economy, and step-efficiency.
