improvement of our own method for synthesising macrocyclic compounds via doubleamidation reactions of aromatic dimethyl esters with five oxa-aliphatic α,ω-diamines of different lengths, leading to a large library of potential ion receptors. We studied the influence of various inorganic salts (NaCl, KCl, CsCl, NH4Cl, MgSO4, CaCl2, CuSO4) on the macrocyclization reaction. The results were analyzed in terms of
我们提出了一种改进的方法,通过芳香族二甲酯与五种不同长度的氧杂脂肪族 α,ω-二胺的双酰胺化反应合成大环化合物,从而产生大量潜在的离子受体。我们研究了各种无机盐(NaCl、KCl、CsCl、NH4Cl、MgSO4、CaCl2、CuSO4)对大环化反应的影响。使用高效液相色谱 (HPLC) 在底物转化和产物分布方面对结果进行分析。
