as the optimal monodentate transient directing group (MonoTDG). Moderate to excellent yields and good selectivity were achieved for a broad substrate scope under mild conditions. More importantly, the synthetic application was demonstrated by a concise two-step total synthesis of the natural product hernandial, which was accomplished by merging this new MonoTDG-assisted C–H iodination and subsequent
                                    在市售的 2,5-
双(三氟甲基)苯胺作为最佳单齿瞬态导向基团 (MonoTDG) 的帮助下,成功开发了第一个
钯催化的
苯甲醛直接o -C-H 
碘化反应。在温和条件下,对于广泛的底物范围,实现了中等至优异的产率和良好的选择性。更重要的是,合成应用通过
天然产物 hernandial 的简明两步全合成得到证明,这是通过合并这种新的 MonoTDG 辅助 C-H 
碘化和随后的
铜催化交叉偶联来完成的。
