Facile and Efficient Synthesis of Hydrophenanthren-1(2H)-ones and Naphtho[2,1-c]furan-3(1H)-ones by a Palladium-Catalyzed Aryne Annulation Strategy

摘要

Novel palladium-catalyzed carboannula-tion reactions of arynes with functionalized vinyl iodides are reported. By applying allyl-substituted io-docycloenones and iodofuranones, a series of hy-drophenanthren-1(2H)-ones and naphtho[2,1-c]furan-3(1H)-ones were efficiently constructed in one pot under mild conditions.
