Strained bicyclic substructures such as bicyclo[1.1.1]pentylamines (BCPAs) are increasingly targeted in medicinal chemistry as arylamine bioisosteres. Here, we leverage high-throughput automated synthesis to rapidly develop library-amenable reaction conditions and maximize design space to expand access to BCPAs. This new protocol relies on a copper-mediated C–N coupling approach and uses accessible and bench-stable iodo-BCP building blocks. Its applicability has been exemplified by incorporating BCPs in drug-like compounds, providing straightforward access to a library of valuable aniline-like isosteres.

双环[1.1.1]戊胺的加速合成：一种高通量方法

双环 [1.1.1] 戊胺 (BCPA) 等应变双环子结构越来越多地作为芳胺生物电子等排物在药物化学中成为目标。在这里，我们利用高通量自动化合成来快速开发适合库的反应条件并最大化设计空间以扩大对 BCPA 的访问。这个新协议依赖于铜介导的 C-N 耦合方法，并使用可访问且稳定的碘-BCP 构建块。它的适用性已通过将 BCP 掺入类药物化合物中得到例证，从而可以直接访问有价值的类苯胺电子等排物库。
