摘要
A series of new 7-aryl-11,12-dihydrobenzo[h]pyrimido-[4,5-b]quinoline-8,10（7H,9H）-diones were synthesized via three-component reaction of aldehydes,l-naphthylamine and barbituric acid in ionic liquid.The method provided several advantages such as easy work-up,high yields and environmentally benign procedure.
