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.

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.

A palladium-catalyzed reductive and carbonylative cyclization of ortho-iodo-tethered methylenecyclopropanes (MCPs) using N-formylsaccharin as CO source has been developed, affording the desired indanone derivatives in moderate to good yields with high regio- and stereoselectivity and good functional group compatibility.
