Boronate ester bullvalenes are now accessible in two to four operationally simple steps. This unlocks late-stage diversification through Suzuki cross-coupling reactions to give mono-, di-, and tri-substituted bullvalenes. Moreover, a linchpin strate-gy enables preprogrammed installation of two dif-ferent substituents. Analysis of solution phase iso-mer distributions and single crystal X-ray structures
现在可以通过两到四个操作简单的步骤获得硼酸酯布瓦烯。这通过铃木交叉偶联反应解锁了后期多样化,以提供单、二和三取代的布瓦烯。此外,关键策略能够预编程安装两个不同的取代基。溶液相异构体分布和单晶 X 射线结构的分析表明,晶格中的异构体偏好是由于一般的形状选择性。
