Electron-deficient nitrogen-containing aromatic heterocycles, particularly pyridine derivatives, can be converted into all-carbon aromatic frameworks via the ANRORC (Addition of Nucleophile, Ring-Opening, and Ring-Closing) skeletal editing process, providing a convenient tool for molecular diversification. However, reported methods are mainly limited to nucleophilic modification of ring-opening species. Herein, we report a distinct electrophilic modification method, smoothly converting pyridines into arene-1,3-dialdehydes or naphthalene-1,3-dialdehydes.
缺电子含氮芳香杂环，特别是吡啶衍生物，可通过亲核试剂加成、开环和闭环（ANRORC）骨架编辑过程转化为全碳芳香骨架，为分子多样化提供了一种便捷工具。然而，已报道的方法主要限于开环物种的亲核修饰。在此，我们报道了一种独特的亲电修饰方法，可将吡啶顺利转化为芳烃-1,3-二醛或萘-1,3-二醛。
