Chemistry of furazano[3,4-<i>b</i>]pyrazines. 2. Nucleophilic substitution of the azido group in furazano[3,4-<i>b</i>]pyrazines

Abstract

The corresponding 7-substituted furazano[3,4-b]tetrazolo[1,2-d]pyrazines were obtained by nucleophilic substitution of the azido group in 7-azidofurazano[3,4-b]tetrazolo[1,2-d]pyrazine. It was shown that these compounds exist in the tetrazole form in the crystalline state; in solutions, a tautomeric equilibrium is observed between the azide and tetrazole forms. Further reaction with nucleophiles leads to the production of 5,6-disubstituted furazano[3,4-b]pyrazines.
