Sulfonic acid-functionalized poly(4-styrenesulfonic acid) mesoporous graphene oxide hybrid for one-pot preparation of coumarin-based pyrido[2,3-d]pyrimidine-dione derivatives

• Sulfonic acid-functionalized poly(4-styrenesulfonic acid) mesoporous graphene oxide hybrid (PSSA-MGO) is prepared by polymerization of 4-styrenesulfonic acid on the surface of mesoporous graphene oxide. The catalyst is fully characterized by several methods including Fourier-transform infrared spectroscopy, Brunauer-Emmett-Teller adsorption-desorption analysis, scanning and transmission electron microscopy. PSSA-MGO is used as an efficient acidic catalyst for the one-pot preparation of some novel chromenopyridopyrimidine-dione derivatives via the three-component reaction of 4-aminocoumarin, thiobarbituric acid and aromatic aldehydes. All the obtained products were also characterized. This synthetic procedure presents some advantages including an eco-friendly procedure, high yield of the products and recyclability of the catalyst.
