A method was developed for the selective amination of 3-R-4,6-dinitrobenzo[d]isoxazoles at position 7 via the oxidative nucleophilic substitution of hydrogen. The resulting nitroamines were used to synthesize representatives of the previously unknown tricyclic heteroaromatic system, viz., isoxazolo[5,4-e]benzofuroxan.
