The title compounds 2 have been synthesized in a one-pot procedure through base-promoted transformation of nitrofurazans 1; the unusual reaction suggested an initial intramolecular nitro-nitrite… Continue Reading
Treatment of 2- and 4-amino-3-(tert-butyl-NNO-azoxy)pyridines with nitrating agents (N2O5or NO2BF4) afforded the first representatives of pyridoannelated 1,2,3,4-tetrazine di-N-oxides, viz.,… Continue Reading
The synthesis of uncondensed 1,2,3-triazole 1-oxides from 4-aminofuroxans has been pioneered.
A comparative analysis of correlations between the ED50 and AD50 values describing the agonist and antagonist properties of opioid receptor ligands, on the one hand, and molecular descriptors related… Continue Reading
Aminoazidofurazan, on treatment with excess sodium nitrite in acetic acid, is converted into the sodium salt of 1-hydroxy-5-cyanotetrazole, crystals of which have been subjected to x-ray diffraction… Continue Reading
Explosive furazans The sequence of introducing the substituents to the target molecule 1, namely initial ether-bond construction and subsequent nitro-NNO-azoxy-group formation, favors the synthesis… Continue Reading
Abstract1(2)-Methyl-5-aminotetrazoles and 2-(Β-cyanoethyl)-5-aminotetrazole are nitrated by tetranitromethane in the presence of bases with the formation of salts of the corresponding… Continue Reading
