One-pot, three-component synthesis of polyfunctionalized benzo[h]pyrazolo[3,4-b][1,6]naphthyridine and benzo[g]pyrazolo[3,4-b]quinoline derivatives in the presence of silver nanoparticles (AgNPs)

An efficient and straightforward protocol for one-pot, three-component reaction of aryl glyoxal monohydrates 1a-h, 5-amino-1-aryl-3-methylpyrazoles 2a,b and 4-hydroxyquinoline-2(1H)-one (3) or 2-hydroxy-1,4-naphthoquinone (4) using silver nanoparticles (AgNPs) as a high performance nanocatalyst in H2O/EtOH at 60°C afforded the corresponding polyfunctionalized benzo[h]pyrazolo[3,4-b][1,6]naphthyridines 5a-h and benzo[g]pyrazolo[3,4-b]quinolines 6a-i, respectively. Excellent catalytic activity, high yields, employing green media and green nanocatalyst, cost-effective and simple procedure are some notable advantages of using AgNPs as a noble metal nanocatalyst in this synthetic strategy. The structures of fused heterocycles were confirmed by their Fourier transform infrared, proton nuclear magnetic resonance (1H-NMR), and 13C-NMR spectral data and microanalysis.
