Synthesis of 1,2,9-trisubstituted purin-6(9H)-ones catalyzed by heteropolyacids

Synthesis of 1,2,9-trisubstituted purin-6(9H)-ones catalyzed by heteropolyacids 1,2,9-Trisubstituted purin-6(9H)-ones have been synthesized in high yield by reaction of 5-amino-N,1-dimethyl-1H-imidazole-4-carboxamide with aromatic aldehydes in the presence of heteropolyacids, H3PMo12O40 and H5PV2Mo10O40. The catalytic activity of H3PMo12O40 is lower than that of H5PV2Mo10O40. This is an effective synthesis of l,2,9-trisubstituted guanine derivatives with the advantages of mild reaction conditions, simple operation, and good yields.
