Chemistry of furazano[3,4-<i>b</i>]pyrazine. 4. 5,6-Dichlorofurazano[3,4-<i>b</i>]pyrazine in cyclization reactions

Abstract

A method was developed for the production of polycyclic compounds containing the furazano[3,4-b]pyrazine fragment by the reaction of difunctional nucleophiles with 5,6-dichlorofurazano[3,4-b]pyrazine. It was shown that the reaction is affected by the hydrogen chloride acceptor (triethylamine).
