explore the application in direct nitroquinoline synthesis, this reaction was subsequently modified as an equivalent reaction in a Schlenk tube. More significantly, after a constant attempt, nitrated derivative was obtained in optimized condition with a zinc(II) sulfate catalyst, where some substrates with strong electron-withdrawing group were first nitrated by a directly catalyzed condition. This new
在这项工作中,我们首先发现了令人惊讶的溶剂热反应,用于喹啉衍生物的直接硝化。为了探索在直接硝基喹啉合成中的应用,随后将该反应修改为Schlenk管中的等效反应。更重要的是,经过不断的尝试,使用硫酸锌(II)催化剂在最佳条件下获得了硝化的衍生物,其中一些具有强吸电子基团的底物首先通过直接催化的条件进行了硝化。这种新的锌(II)催化的芳族CH活化反应是单一催化剂直接硝化的第一个例子,这将是一种获得合成上有用的硝基喹啉衍生物的简便,环保的策略。
