TL;DR: In this paper, a general two-step approach for direct synthesis of (1H-tetrazol-5-yl)furoxan ammonium salts with various functional substituents based on initial effective synthesis of cyanofuroxans by dehydration of furoxancarboxylic acid amides by the action of (CF3CO)2O/Py followed by [3+2]-cycloaddition of the cyanofurusans to ammonium azide, generated in situ from TMSN3 and NH4F, has been

TL;DR: New high-energy materials based on isomeric dinitrobi-1,2,5-oxadiazole structures comprising nitrofurazan and nitrofuroxan subunits were synthesized and display high density values as determined by single-crystal X-ray diffraction.

TL;DR: One-pot protocols for the synthesis of previously unknown hybrid heterocyclic systems with the furoxanylpyridine core based on the tandem inverse-electron-demand hetero-Diels-Alder/retroDiels−Alder reactions of the tailor-made (1,2,4-triazin-3-yl)furoxans with 1-(pyrrolidino)cyclohexene and norbornadiene have been developed.

TL;DR: Several energy-rich bifuroxans incorporating nitro and azido functionalities have been synthesized and thoroughly characterized by IR and multinuclear NMR spectroscopy, elemental analyses, single-c...

TL;DR: In this article, a regioselective method for the synthesis of previously unknown bifuroxanyl systems containing the 3-nitro-drugs core was proposed, based on a cascade of one-pot reactions.
