  Reactions of 5-nitrospiro[benzimidazole-2,1′-cyclohexane] 1,3-dioxide with nucleophiles

  摘要：

  Reactions of 5-nitrospiro[benzimidazole-2,1'-cyclohexane] 1,3-dioxide with aliphatic amines and sodium hydroxide resulted in removal of one N-oxide oxygen atom and formation of 4-alkylamino- or 4-hydroxy-substituted 5-nitrospiro[benzimidazole-2,1'-cyclohexane] 1-oxides, respectively. The title compound reacted with ammonia and methylamine in the presence of MnO2 with conservation of both N-oxide moieties, and the products were 4-amino- and 4-methylamino-5-nitrospiro[benzimidazole-2,1'-cyclohexane] 1,3-dioxides. The reactions with aromatic amines were accompanied by removal of both N-oxide oxygen atoms with formation of N-aryl-5-nitrospiro[benzimidazole-2,1'-cyclohexane]-4-amines. In the reactions of 5-nitrospiro[ benzimidazole-2,1'-cyclohexane] 1,3-dioxide with sodium azide and aromatic amine hydrochlorides nucleophilic replacement of the 5-nitro group by azido or arylamino occurred, in the first case both N-oxide fragments being conserved. The reactions with aromatic amine hydrochlorides afforded N-aryl-5-nitrospiro[benzimidazole-2,1'-cyclohexan]-4-amine 1-oxides. Treatment of 5-nitrospiro[benzimidazole-2,1'-cyclohexane] 1,3-dioxide with sodium cyanide led to the formation of 5-oxo-3,5-dihydrospiro[benzimidazole-2,1'-cyclohexane]-4-carbonitrile 1-oxide.
