An efficient and green approach has been developed for the synthesis of 2-substituted 2,3-dihydroquinazolin-4(1H)-ones directly from corresponding substituted aromatic and aliphatic aldehyde and anthranilamide using recyclable polymer supported sulfonic acid catalyst under aqueous conditions. Environmental acceptability, operational simplicity, low cost, excellent functional group compatibility, and
已经开发了一种有效的绿色方法,用于在水性条件下,使用可回收的聚合物负载的磺酸催化剂,直接从相应的取代的芳族和脂肪族醛以及邻氨基苯甲酰胺中合成2取代的2,3-二氢喹唑啉-4(1 H)-。环境可接受性,操作简便性,低成本,出色的官能团兼容性和高收率是该协议的重要特征。
