Azoxyarenes are among important scaffolds in organic molecules. Direct oxidative coupling of primary anilines provides a concise fashion to construct them. However, whether these scaffolds can be prepared from secondary N-alkylanilines is not well explored. Here, we present a catalytic selective oxidative coupling of secondary N-alkylaniline to afford azoxyarene with tungsten catalyst under mild conditions
叠氮芳烃是有机分子中重要的支架之一。初级苯胺的直接氧化偶联为构建它们提供了一种简洁的方法。然而,这些支架是否可以由仲N-烷基苯胺制备尚未得到很好的研究。在这里,我们提出了在温和条件下仲N-烷基苯胺催化选择性氧化偶联以提供具有钨催化剂的叠氮芳烃。另外,a氧基可被视为烯烃和酰胺的生物等排体。相应的生物活性烯烃和酰胺的几种“偶氮芳烃类似物”显示出可比的有希望的抗癌活性。
