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, tetrahydropyranofurans, and dihydrobenzofurans
在碘代苯二乙酸酯,全氟化醇和呋喃,烯丙基硅烷或环状烯醇醚的存在下处理各种取代的苯酚可促进氧化环化过程,产率中等至有用。在仅一步中,该方法产生不同的杂环,例如二氢呋喃苯并呋喃,四氢呋喃苯并呋喃,四氢吡喃呋喃和二氢苯并呋喃。
