The synthesis of suramin analogues bearing a 2‐phenyl‐benzimidazole moiety is described. Aminoarene sulfonic acids 2a–e are acylated with 3,4‐dinitrobenzoyl chloride 3 yielding the amides 4a‐e which are hydrogenated to the corresponding diamines 5a‐e. These are treated with 3‐nitrobenzaldehyde, yielding the azomethines 7a‐e and their isomers 8a‐e and 9a‐e. Key step in the synthesis of the target compounds
描述了带有 2-苯基-苯并咪唑部分的苏拉明类似物的合成。氨基芳烃磺酸 2a-e 用 3,4-二硝基苯甲酰氯 3 酰化,生成酰胺 4a-e,再氢化成相应的二胺 5a-e。这些用 3-硝基苯甲醛处理,产生偶氮甲碱 7a-e 及其异构体 8a-e 和 9a-e。合成目标化合物 12a-e 的关键步骤是用氧将偶氮甲碱氧化成苯并咪唑 10a-e。这些被氢化成胺11a-e,与光气反应产生对称的脲12a-e。提供了抗 HIV、细胞抑制和抗血管生成筛查的结果。
