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, 1-naphthylamine and barbituric acid in ionic liquid. The method provided several advantages such as easy work-up, high yields and environmentally benign procedure.
- Aldehyde,
- 1-Naphthylamine,
