palladium/XPhos complex and 5-norbornene-2-carboxylic acid was developed. This system promotes a two-component annulation reaction, allowing the construction of tetrahydronaphthalenes and indanes that contain quaternary centers through consecutive Catellani-type C–H activation and redox-relay Heck reaction. Inexpensive 5-norbornene-2-carboxylic acid acts as a catalytic mediator (20 mol %) in this process. This mild
开发了包含
钯/ XPhos配合物和
5-降冰片烯-2-羧酸的协同催化体系。该系统促进了两组分环化反应,从而通过连续的Catellani型C–H活化和氧化还原中继Heck反应,构建了含有四级中心的四氢
萘和
茚满。廉价的
5-降冰片烯-2-羧酸在该方法中充当催化介体(20mol%)。这种温和的,可扩展的和
化学选择性的方案与各种现成的芳基
碘化物和烷基化试剂兼容。证明了该方法在阿片类镇痛肽唑嗪的4步合成中的应用。初步研究强调了将这种Catellani /氧化还原中继Heck级联反应对映选择性的未来前景。
