Triazole assistance enabled the first iron‐catalyzed C−H alkynylation of arenes, heteroarenes, and alkenes. The modular TAM directing group set the stage for a sequential C−H alkynylation/annulation strategy with ample scope, enabling the iron‐catalyzed assembly of isoquinolones, pyridones, pyrrolones, and isoindolinones with high levels of chemo‐, site‐, and regioselectivity.
三唑的辅助作用使芳烃,杂芳烃和烯烃的首次铁催化CH炔基化反应成为可能。模块化的TAM指导小组为具有足够范围的顺序C-H炔基化/环化策略奠定了基础,使铁催化的异喹诺酮,吡啶酮,吡咯烷酮和异吲哚啉酮具有化学,位点和区域选择性高水平的组装能力。
