A large array of 3-methylene tetrahydrofurans has been synthesized from propargylic alcohols and activated olefins. The reaction is promoted by copper iodide that is removed at the end of the reaction by simple filtration, affording the desired heterocycles in high yield and purity.
已经从炔丙醇和活化的烯烃合成了大量的3-亚甲基四氢呋喃。通过碘化铜促进反应,该碘化铜在反应结束时通过简单过滤除去,从而以高收率和纯度提供所需的杂环。
