deuteration of organic entities. Here, we present a highly effective regioselective direct C–H deuteration of indole in D2O using Cp*Co(CO)I2, [Cp*RhCl2]2, or their combination as a catalyst. This transition-metal-catalyzed system made available mono(C2)-, di(C2/C7)-, tri(C2/C3/C7)-, and even C4-deuterated products from diverse indole substrates, equipped with the removable N1-directing group. The selective
氘标记的化合物(例如药物氘苯丁嗪)的有前途的应用保证了有机实体的高效,选择性和直接氘化。在这里,我们介绍了使用Cp * Co(CO)I 2,[Cp * RhCl 2 ] 2对D 2 O中的吲哚进行区域选择性直接C H重排的高效方法,或它们的组合作为催化剂。这种过渡金属催化的系统可从各种吲哚底物中获得单(C2)-,二(C2 / C7)-,三(C2 / C3 / C7)-甚至C4氘代产品,并配有可移动的N1-指导小组。吲哚其余部位的选择性H / D交换也通过转移指导基团来实现。此外,该方法的一个实例证明可以从药物褪黑激素中获得氘代褪黑激素。
