the synthesis of benzoxazinones requires transition‐metal catalysts and pre‐functionalized substrates such as aryl halides. However, the anodic C−H amination of phenoxy acetates offers a very efficient and sustainable access to these heterocycles. The presented electrochemical protocol can be applied to a broad scope of alkylated substrates. Even tert‐butyl moieties or halogen substituents are compatible
1,4-苯并恶嗪-3-酮是天然产物和生物活性化合物中的重要结构基序。通常,苯并恶嗪酮的合成需要过渡金属催化剂和预官能化的底物,例如芳基卤化物。但是,乙酸苯氧基的阳极CH氨基化可非常有效且可持续地访问这些杂环。提出的电化学方案可以应用于广泛的烷基化底物。甚至叔丁基部分或卤素取代基也与这种通用方法兼容。
