nitrogen-to-carbon skeletal editing. This approach proceeds via a sequence of pyridine ring-opening, imine hydrolysis, olefination, electrocyclization, and aromatization to achieve the desired transmutation. The most notable features of this transformation are the ability to directly install a wide variety of versatile functional groups in the benzene scaffolding, including ester, ketone, amide, nitrile
芳香系统中单个原子的定向和选择性替换代表了分子支架快速相互转化的强大策略。在此,我们报告了通过氮到碳骨架编辑的
吡啶到苯的转化。该方法通过一系列
吡啶开环、
亚胺水解、烯化、电环化和芳构化来实现所需的转化。这种转变最显着的特点是能够在苯骨架中直接安装各种多功能官能团,包括酯、酮、酰胺、腈和
磷酸酯片段,以及包含间位取代的
吡啶,迄今为止,相关策略还难以捉摸。
