A simple, straightforward and efficient method is described for the synthesis of 5-aryl-1H-indeno[2’,1’:5,6]pyrido[2,3-d]pyrimidine-2,4,6(3H)-trione via one-pot multicomponent reaction of indane-1,3-dione, arylaldehydes and 6-aminopyrimidin-2,4(1H,3H)-dione in presence of catalytic amount of graphene oxide in water. Graphene oxide is a versatile carbocatalyst and this is the first report on its application in a pyrido[2,3-d]pyrimidine synthesis. Good yield, use of readily available starting materials, operational simplicity, easy work-up and eco-friendly re-usable catalyst are the key features of this protocol.
