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(
