Sergievskii, A. V. published the artcile4-Aminofurazan-3-carboxylic Acid Iminoester in Reactions with N,O-Nucleophiles, Formula: C9H7N5O, the publication is Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii) (2002), 38(6), 872-874, database is CAplus.
Reactions of 4-aminofurazan-3-carboxylic acid iminoester with o-aminophenol and ethylenediamine give rise resp. to 4-(1,3-benzoxazol-2-yl)- and 1-(4,5-dihydro-1H-imidazol-2-yl)-1,2,5-oxadiazol-3-amines, with aminoethanol arises 2-[(Z)-1-amino-1-(4-amino-1,2,5-oxadiazol-3-yl)methylideneamino]-1-ethanol. Treating of 3-amino-4-(1H-benzo[d]imidazol-2-yl)-1,2,5-oxadiazole with tri-Et orthoformate in acetic anhydride yielded benzo[4,5]imidazo[1,2-c][1,2,5]oxadiazolo[3,4-e]pyrimidine, and alkylation with haloalkanes furnished 3-amino-4-(1-R-benzo[d]imidazol-2-yl)-1,2,5-oxadiazoles.
Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii) published new progress about 332026-86-5. 332026-86-5 belongs to imidazoles-derivatives, auxiliary class Oxadiazole,Amine,Benzimidazole, name is 4-(1H-Benzo[d]imidazol-2-yl)-1,2,5-oxadiazol-3-amine, and the molecular formula is C7H8O3, Formula: C9H7N5O.
