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.
The interaction of 4,6-dinitrobenzo[d]isoxazole-3-carbonitrile (5a) with methoxideion has been kineticallyinvestigated in methanol and a 20:80 (v/v) MeOH-Me2SO mixture. In methanol, stopped-flow experiments have revealed that a monomethoxyl σ-adduct (5a-Me) is first formed, resulting from a fast MeO− addition at the unsubstituted 7-carbon.

Pericyclic [4+2] cycloaddition (Diels-Alder reaction) of nitrofuroxanobenzo[d]isoxazoles, capable of acting both as dienophiles (at the C=CNO2 bond) or heterodienes (at the C=C-N(O)=O fragment) was used to synthesize a new type of condensed polycyclic systems. The obtained compounds combining in one molecule two pharmacophore moieties, furoxan (nitric oxide donor) and substituted isoxazole, may be considered as a potential basis for the design of compounds with dual biological activity.

The action of various anionic O-, N-, and S-nucleophiles on 3-cyano-4,6-dinitro-benzo[d]isoxazole mostly resulted in regiospecific nucleophilic substitution for the nitro group in position 4. With an excess of an nucleophilic reagent, the nitro group in position 6 was also replaced.
