  benzoannulation are reported. The first strategy is based on the Suzuki–Miyaura cross-coupling reaction. To this end, various ortho-diallylbenzene derivatives were prepared from the corrresponding diiodo derivatives by an allylation strategy using an allylboronate as coupling partner. These diallyl derivatives were subjected to a ring-closing metathesis (RCM) and one-pot dichlorodicyanoquinone (DDQ) oxidation

  报道了两种新的苯并环合合成策略。第一个策略是基于Suzuki-Miyaura交叉耦合反应。为此，使用烯丙基硼酸酯作为偶联伙伴，通过烯丙基化策略从相应的二碘代衍生物制备了各种邻二烯丙基苯衍生物。对这些二烯丙基衍生物进行闭环复分解（RCM）和一锅法二氯二氰基醌（DDQ）氧化，以生成2-取代的萘。在第二种策略中，使用双重Claisen重排和RCM协议作为关键步骤，以生成高度官能化的苯并苯基醌衍生物。
