A straightforward method for the synthesis of highly functionalized vinylarenes through palladium‐catalyzed, norbornene‐mediated CH activation/carbene migratory insertion is described. Extension to a one‐pot procedure is also developed. Furthermore, this method can also be used to generate polysubstituted bicyclic molecules. The reaction proceeds under mild conditions to give the products in satisfactory
描述了一种通过钯催化,降冰片烯介导的CH活化/卡宾迁移插入合成高度官能化乙烯基芳烃的简单方法。还开发了扩展到一锅法的程序。此外,该方法也可以用于产生多取代的双环分子。反应在温和的条件下进行,使用容易获得的起始原料,以令人满意的产率得到产物。这是Catellani–Lautens反应,其中包含不同类型的偶联伙伴。此外,该反应是第一个证明将Pd催化的重氮化合物插入与Pd催化的CH活化相结合的反应。
