We describe a novel one-pot three-step reaction of 2-alkynyl arylazides through palladium-catalyzed formation of 3-hydroxy-3-phenylindolin-2-ones followed by hydrolysis of amide bonds and copper-catalyzed decarboxylation to give 2-aminobenzophenones. This synthetic method works well with various 2-alkynyl arylazides and affords the products in moderate to good yields under mild reaction conditions.

In this paper, we revealed a metal-free and visible light photoinduced method for the rapid construction of spirobi[indene] skeletons, providing a simple and efficient way for easy access to spirobi[indene] scaffolds under mild conditions along with a broad substrate scope and good functional group tolerance.
Synthesis of Diiodinated All-Carbon 3,3′-Diphenyl-1,1′-spirobiindene Derivatives via Cascade Enyne Cyclization and Electrophilic Aromatic Substitution

A synthetic method for the construction of diiodinated all-carbon spirobiindene derivatives has been developed from the reaction of propargyl alcohol-tethered alkylidenecyclopropanes with iodine. The reaction proceeded through an iodination-initiated cascade intramolecular enyne cyclization and electrophilic aromatic substitution reaction process in 1,2-dichloroethane upon heating, giving desired spirocyclic products in moderate to excellent yields. Further transformation of the obtained products has also been presented.
