Here, we explore the GO‐catalyzed cross‐dehydrogenative coupling of oxindoles with arenes and thiophenols for the rapid synthesis of 3‐aryloxindoles and 3‐sulfenylated oxindoles. Control experiments and small‐molecule mimicking studies reveal that the acidic nature and quinone‐type functionalities of GO are synergistically utilized for the coupling reaction. The reaction proceeds under simple and mild
在这里,我们探索了GO催化的羟吲哚与芳烃和硫酚的交叉脱氢偶联,用于快速合成3芳基羟吲哚和3磺酰化的羟吲哚。对照实验和小分子模拟研究表明,GO的酸性和醌型官能团可用于协同反应。反应在简单温和的反应条件下进行,具有良好的官能团耐受性,可以轻松按比例放大至克级。
