The preparation of a new macro-ring compound, 9, 18, 27-triaza-10, 19, 28-trioxo-35-pentatriacontanelactam, is described. A simple azide method in a mixed solvent system (water : dimethylformamide (DMF)=1 : 3) gave a good cyclization result, and the use of sodium or potassium cations as a template produced a 30% augmentation in the yield.
本文介绍了一种新的大环化合物--9, 18, 27-三氮杂-10, 19, 28-三氧杂-35-戊内酰胺的制备方法。在混合溶剂体系(水:二甲基甲酰胺 (DMF)=1 : 3)中采用简单的叠氮方法可获得良好的环化效果,使用钠或钾阳离子作为模板可使产率提高 30%。
