three‐component cascade reaction has been used to construct structurally diverse pyrrolo[1,2‐c]quinazolinone derivatives with potential biological activities. This method has advantages of mild conditions, simple work‐up, as well as wide substrate scope, which makes it a powerful approach to the synthesis of diverse pyrrolo[1,2‐c]quinazolinones. This cascade reaction involves 1,3‐dipolar cycloaddition between
意外的FeCl 3介导的三组分级联反应已被用于构建具有潜在生物活性的结构不同的吡咯并[1,2- c ]喹唑啉酮衍生物。该方法具有条件温和,后处理简单以及底物范围广的优点,这使其成为合成各种吡咯并[1,2- c ]喹唑啉酮的有力方法。该级联反应包括在甲亚胺基化物和脲基甲酸酯之间进行1,3-偶极环加成,然后在存在FeCl 3的情况下进行分子内亲核加成。获得的产物可以很容易地转化为具有吡咯并[2,3- c ]喹唑啉生物碱骨架的衍生物。
