palladium-catalyzed process to access highly functionalized, optically active allylic aryl ethers. A number of electron-deficient alkenyl triflates underwent enantioselective and site-selective coupling with acyclic aryl enol ethers in the presence of a chiral palladium catalyst. This transform provides chiral allylic ether products in high yields and excellent enantiomeric ratios, furnishing a unique
该报告详细介绍了一种钯催化的工艺,用于获取高功能化、光学活性的烯丙基芳基醚。许多缺电子烯基三氟甲磺酸酯在手性钯催化剂存在下与无环芳基烯醇醚进行对映选择性和位点选择性偶联。这种转化以高产率和优异的对映体比例提供了手性烯丙醚产物,提供了独特的断开以在立构中心掺入杂原子。最后,通过手性烯丙醇的形成和黄酮类产品的生成,证明了产品对目标合成的适用性。
