The oxidative treatment of (m)ethyl 2-aryl cinnamates equipped with methoxy groups in position 4 of the phenyl moiety promote the formation of cyclohexadienone substructures. This dealkylative oxidative C–C coupling gives access to spirocyclic compounds and avoids the construction of the corresponding phenanthrenes. Furthermore, the transformation can be expanded to other spirocyclic systems.
在苯基部分的 4 位带有甲氧基的(m)乙基 2-芳基肉桂酸酯的氧化处理促进了环己二烯酮亚结构的形成。这种脱烷基氧化性 C-C 偶联提供了获得螺环化合物的途径,并避免了相应菲的构建。此外,转化可以扩展到其他螺环系统。
