On-water synthesis of 2-substituted quinolines from 2-aminochalcone derivatives was developed using benzylamine as the nucleophilic catalyst. Various 2-aminochalcones could be applied to this protocol, and the desired 2-substituted quinoline products were isolated in excellent yields by simple filtration. Furthermore, we elucidated the role of benzylamine in this transformation and provided the detailed
使用苄胺作为亲核催化剂,开发了由2-氨基查尔酮衍生物在水上合成2-取代的喹啉的方法。可以将各种2-氨基查耳酮应用于该方案,并通过简单过滤以优异的产率分离出所需的2-取代的喹啉产物。此外,我们阐明了苄胺在该转化中的作用并提供了详细的反应机理。该方案具有其他优点,例如操作简单,底物范围广,官能团耐受性好,产物易于分离,催化剂的循环利用和克级合成。
