Cascade reactions are an important strategy in reaction design, allowing streamlining of chemical synthesis. Here we report a cascade Suzuki–Miyaura/Diels–Alder reaction, employing vinyl Bpin as a bifunctional reagent in two distinct roles: as an organoboron nucleophile for cross-coupling and as a Diels–Alder dienophile. Merging these two reactions enables a rapid and operationally simple synthesis
级联反应是反应设计中的重要策略,可以简化化学合成。在这里,我们报告了级联 Suzuki-Miyaura/Diels-Alder 反应,使用乙烯基 Bpin 作为双功能试剂,具有两种不同的作用:作为交叉偶联的有机硼亲核试剂和作为 Diels-Alder 亲核试剂。合并这两个反应能够以良好的产率快速且操作简单地合成官能化碳环。研究了有机硼亚型对 Diels-Alder 区域选择性的影响,并在模型底物上进行了合成后修饰。还评估了补充 Heck/Diels-Alder 工艺的潜力。
