  最近，真菌鞘脂糖基神经酰胺（GlcCer）的合成已成为下一代抗真菌药的药物开发的高度有希望的新目标，我们基于HTP筛选发现了两种芳香族酰基hydr作为GlcCer合成的有效抑制剂。在目前的工作中，我们设计了新的芳香族酰基hydr的文库，评估了它们对新孢子虫的抗真菌活性（MIC80和时间杀灭谱），并进行了广泛的SAR研究，从而鉴定了五种有前途的先导化合物，极高的选择性指数，具有出色的杀真菌活性。此外，两种化合物对其他六种临床相关真菌菌株均具有广谱抗真菌活性。研究了这五种先导化合物与五种临床药物对七种真菌菌株的协同作用/协同作用，并获得了令人鼓舞的结果。例如，所有五个先导化合物与伏立康唑的组合对所有七个真菌菌株均表现出协同作用或加和作用。

  method enables non‐directed functionalization of C−H bonds on a range of substrates, providing access to aryl trifluoromethyl ethers. This light‐driven process is distinctly different from conventional procedures and occurs through an OCF3 radical mechanism mediated by a photoredox catalyst, which triggers an N−O bond fragmentation. The pyridinium‐based trifluoromethoxylation reagent is bench‐stable and

  The intermolecular C−H trifluoromethoxylation of arenes remains a long‐standing and unsolved problem in organic synthesis. Herein, we report the first catalytic protocol employing a novel trifluoromethoxylating reagent and redox‐active catalysts for the direct (hetero)aryl C−H trifluoromethoxylation. Our approach is operationally simple, proceeds at room temperature, uses easy‐to‐handle reagents, requires

  芳烃的分子间CH-C三氟甲氧基化仍然是有机合成中长期存在且未解决的问题。在此，我们报告了第一个采用新型三氟甲氧基化试剂和氧化还原活性催化剂进行直接（杂）芳基 C−H 三氟甲氧基化的催化方案。我们的方法操作简单，在室温下进行，使用易于处理的试剂，仅需要 0.03 mol% 的氧化还原活性催化剂，不需要专门的反应设备，并且可以耐受多种官能团和复杂结构，例如糖和天然产物衍生物。重要的是，基态和光激发氧化还原活性催化剂都是有效的。详细的计算和实验研究表明了一种独特的反应途径，其中三氟甲氧基化试剂的光激发释放被（杂）芳烃捕获的 OCF 3自由基。所得环己二烯基自由基被氧化还原活性催化剂氧化并去质子化，形成所需的三氟甲氧基化产物。

  importantly, the reagent allows catalytic, intermolecular C−H trifluoromethoxylation of a broad array of (hetero)arenes and biorelevant compounds. Experimental and computational studies suggest single electron transfer (SET) from excited photoredox catalysts to 1 resulting in exclusive liberation of the OCF3 radical. Addition of this radical to (hetero)arenes gives trifluoromethoxylated cyclohexadienyl radicals
