A short and simple synthesis of chromeno[3,4-b][4,7]phenanthroline derivatives was accomplished by three-component reactions involving an aromatic aldehyde, 6-aminoquinoline and 4-hydroxycoumarin in water, under microwave irradiation without use of any catalyst. This protocol has the advantages of short reaction time, high yields, low cost and being environmental-friendly as well as easy operation
在水中不进行任何微波辐射的情况下,通过三组分反应(包括芳族醛,6-氨基喹啉和4-羟基香豆素)在水中进行了三组分反应,从而完成了铬诺[3,4- b ] [4,7]菲咯啉衍生物的简短合成。催化剂。该方案具有反应时间短,收率高,成本低,环保,操作简便的优点。
