α-Pyridyl tertiary amino acids have potential pharmaceutical applications because of their structural features. However, their synthesis is still highly limited. Herein, we report a straightforward approach for the electrochemical synthesis of tertiary α-substituted amino acid derivatives via three-component reductive coupling. Using gaseous ammonia as both the N and H source, the α-keto ester reacts
α-吡啶基叔氨基酸由于其结构特征而具有潜在的药物应用。然而,它们的合成仍然非常有限。在此,我们报告了一种通过三组分还原偶联电化学合成叔α-取代氨基酸衍生物的简单方法。使用气态氨作为 N 源和 H 源,α-酮酯直接与 4-CN-吡啶反应。钪催化的应用是实现各种副反应途径化学选择性的关键。
