Abstract

The iodine-catalyzed reaction of 2-(2-aminophenyl)quinazolin-4(3H)-ones and benzaldehydes was treated in ionic liquids, giving a series of 6-aryl-5H-quinazolino[4,3-b]quinazolin-8(6H)-one derivatives in high yields. This novel procedure has the advantages of high yields, being metal-free and having a mild reaction condition.
