the nitro group and condensation with ethoxycarbonylisothiocyanate to give 6-benzyl-2-ethoxycarbonylamino-1H-imidazo[4,5-d]pyridine (8). The ethoxycarbonyl moiety of 8 was cleaved, N-1 was isopropylsulfonylated, and the carbonyl moiety was condensed with hydroxylamine to give 1. Compound 1 was inactive against rhinovirus 1B and poliovirus type 1.
6-[[(羟基亚氨基)苯基]甲基] -1-[(1-甲基乙基)磺酰基] -1 H-咪唑并[4,5 - b ]吡啶-2-胺(1),是一种环境肟的氮杂类似物。由6个羟基烟酸(2)分八步合成。将酸2硝化,用五氯化磷氯化,然后进行Friedel-Crafts芳构化,得到6-氯-5-硝基-3-吡啶基苯基酮(5)。5的胺化之后,还原硝基并与乙氧基羰基异硫氰酸酯缩合,得到6-苄基-2-乙氧基羰基氨基-1 H-咪唑并[4,5- d ]吡啶(8)。8的乙氧羰基部分裂解N 1,将N-1异丙基磺酰化,并将羰基部分与羟胺缩合,得到1。化合物1对鼻病毒1B和脊髓灰质炎1型无活性。
