摘要

The pyrazolo [3, 4-d][1, 2, 3] triazin-4-ones 3 and imidazo [4, 5-d][1, 2, 3] triazin-4-ones 4 are analogs structurally related to purines that have showed a wide and significant variety of biological activity. These compounds were synthesized by one-pot diazotization of 5-amino- 1H-pyrazole-4-carbonitriles 1 and 5-amino-1H-imidazole-4-carbonitriles 2, respectively.
