Preparation of Pyrano[3,2-c]chromene-3carbonitriles using Sulfonic Acid-Functionalized Graphene Oxide Catalysts

In this research sulfonic acid-functionalized graphene oxide as an effective solid acid catalyst used for promotion of the synthesis of pyrano [3,2-c]chromene-3-carbonitrile (PCC) derivatives via one-pot three-component condensation through a domino Knoevenagel/Michael/cyclization sequence. The attractive features of this process are simple procedures, short reaction times, high yields, no column chromatographic separation, commercial availability of the starting materials and recyclability of the catalyst
