One-pot Synthesis Benzopyrano[۲,۳-d]pyrimidine Derivatives Using Copper Nanocatalyst Stabilized On Graphene Oxide Functionalized by N۱,N۲-bis((pyridine-۲-yl)methyl)benzene-۱,۲-diamine

Copper nanocatalyst stabilized on graphene oxide functionalized by N۱,N۲-bis((pyridine-۲-yl)methyl)benzene-۱,۲-diamine was designed and synthesized as a bifunctional catalyst. It was used to synthesis benzopyrano[۲,۳-d]pyrimidine via a one-pot and three-component condensation reaction of aromatic aldehydes, malononitrile and cyclic amines. The structure of the mentioned compound was fully characterized by using several techniques including FT-IR, H-NMR, EDX, SEM, TGA. The catalyst was easily recovered. The products were obtained in a green condition with high yield
