Herein, a novel method for the gram-scale synthesis of (E)-quinoxalinone oximes through a multicomponent reaction under mild conditions is described. Such a transformation was performed under transition-metal-free conditions, affording (E)-oximes in a moderate-to-good yield through recrystallization. Our methodology demonstrates a successful combination of a Mannich-type reaction and radical coupling
在此,描述了在温和条件下通过多组分反应用于克级合成(E)-喹喔啉酮肟的新方法。这种转变是在无过渡金属的条件下进行的,通过重结晶以中等至良好的产率提供(E)-肟。我们的方法论证明了曼尼希型反应和自由基偶联的成功结合,为合成具有潜在生物活性的含喹喔啉酮的分子提供了绿色实用的方法。
