The palladium-catalyzed oxidation of alkyl enol ethers to enals, which employs low loadings of a palladium catalyst, is described. The mild oxidation conditions tolerate a diverse array of functional groups, while allowing the formation of di-, tri-, and tetrasubtituted olefins. The application of this methodology to intramolecular reactions of alkyl enol ethers containing pendant alcohols provides
描述了使用低负载量的钯催化剂的钯催化的烯醇醚氧化为烯醛。温和的氧化条件可耐受各种官能团,同时允许形成二,三和四取代的烯烃。该方法在含有侧链醇的烷基烯醇醚的分子内反应中的应用提供了呋喃和2,5-二氢呋喃产物。
