摘要：

Treatment of various substituted phenols in the presence of iodobenzene diacetate, perfluorinated alcohols and furan, allylsilanes or cyclic enol ethers promotes an oxidative annulation process in moderate to useful yields. In only one step, this method produces different heterocyclic rings such as dihydrofuranobenzofurans, tetrahydrofuranobenzofurans, tetra hydropyranofurans, and dihydrobenzofurans.
