Synthesis of 2-aryl-2,3-dihydroquinazoline-4(1H)-ones is described by using new and novel heterogeneous catalyst, Indion Ina 225H resin. Anthranilamide was reacted with a series of aromatic aldehydes in presence of resin to afford various 2-aryl substituted 2,3-dihydroquinazoline-4(1H)-ones. The resin employed in these reactions can be recovered and reused.
使用新型异相催化剂 Indion Ina 225H 树脂合成了 2-芳基-2,3-二氢喹唑啉-4(1H)-酮。在树脂存在下,蒽酰胺与一系列芳香醛发生反应,生成各种 2-芳基取代的 2,3-二氢喹唑啉-4(1H)-酮。在这些反应中使用的树脂可以回收和重复使用。
