A general, efficient and practical method for the synthesis of 3-alkylidenefuran-2-ones has been developed from readily accessible aryl iodides and benzyl acetylenes via a recyclable palladium-catalyzedcarbonylative coupling reaction in a green solvent 2-MeTHF. The reaction proceeds smoothly under a CO atmosphere and mild conditions, yielding a wide range of furanones in good to excellent yields.
通过在绿色溶剂 2-MeTHF 中进行可回收的钯催化的羰基化偶联反应,由易于获得的芳基碘和苄基乙炔开发了一种通用、有效且实用的合成 3-亚烷基呋喃-2-酮的方法。反应在 CO 气氛和温和条件下顺利进行,以良好到优异的收率产生各种呋喃酮。
