  Intermolecular C–H difluoromethoxylation of (hetero)arenes remains a long-standing and unsolved problem in organic synthesis. Herein, we report the first catalytic protocol employing a redox-active difluoromethoxylating reagent 1a and photoredox catalysts for the direct C–H difluoromethoxylation of (hetero)arenes. Our approach is operationally simple, proceeds at room temperature, and uses bench-stable

  （杂）芳烃的分子间CH-H二氟甲氧基化在有机合成中仍然是一个长期存在且尚未解决的问题。在这里，我们报道了第一个使用氧化还原活性二氟甲氧基化试剂1a和光氧化还原催化剂对（杂）芳烃进行直接CHH二氟甲氧基化的催化方案。我们的方法操作简便，可在室温下进行，并使用稳定的试剂。其温和的反应条件可耐受多种官能团和生物相关分子，从而突出了其合成用途。实验和计算研究表明，单电子转移（SET）从激发的光氧化还原催化剂到1a，形成释放OCF 2的中性自由基中间体仅氢自由基。将该自由基加到（杂）芳烃上，得到二氟甲氧基化的环己二烯基，其被氧化和去质子化，得到二氟甲氧基化的产物。

  Lysyl oxidase (LOX) is a secreted copper-dependent amine oxidase that cross-links collagens and elastin in the extracellular matrix and is a critical mediator of tumor growth and metastatic spread. LOX is a target for cancer therapy, and thus the search for therapeutic agents against LOX has been widely sought. We report herein the medicinal chemistry discovery of a series of LOX inhibitors bearing

  赖氨酰氧化酶（LOX）是一种分泌型铜依赖性胺氧化酶，可在细胞外基质中交联胶原蛋白和弹性蛋白，并且是肿瘤生长和转移性扩散的关键介质。LOX是癌症治疗的靶标，因此已经广泛寻求抗LOX的治疗剂。我们在这里报告了一系列带有氨基亚甲基噻吩（AMT）支架的LOX抑制剂的药物化学发现。高通量筛选提供了最初的结果。结构活性关系（SAR）研究导致在LOX酶活性测定中发现亚微摩尔半数最大抑制浓度（IC50）的AMT抑制剂。进一步的SAR优化产生了口服生物可用的LOX抑制剂CCT365623，具有良好的抗LOX效能，选择性，药代动力学特性，
