Abstract The synthesis of benzene-1, 4-bis(carboxamido-N,N-bis(acetyldiglicylglycinamide-N′-ethyl-2-N″-carbomoyl-(3,7-dimethoxy-2-naphthalene) by the method allowing one to avoid its tedious purification and unsuccessful attempts to obtain its quadruple complexes with native cyclodextrins are described. Molecular modeling of diglicylglycinamide-N′-ethyl-2-N″-carbomoyl-(3,7-dimethoxy-2-naphthalene)
摘要 苯-1, 4-双(甲酰氨基-N,N-双(乙酰二甘基甘氨酰胺-N'-乙基-2-N"-carbomoyl-(3,7-dimethoxy-2-naphthalene))的合成方法允许一种为了避免其繁琐的纯化和不成功的尝试获得其与天然环糊精的四重复合物,描述了二甘氨酰胺-N'-乙基-2-N″-carbomoyl-(3,7-二甲氧基-2-萘)模拟树枝状聚合物的分子模型分支表明复合物应该形成。然而,在核磁共振谱和色谱测量中没有检测到复合物的表现。树枝状大分子本身的分子模型表明,芳族端基的成对堆积可能是造成缺乏的原因络合。
