A series of new hetero-macrocyclic diamide-ester compounds (4a — 4z, 6a — 6b) were synthesized using 4-(dimethylamino)pyridine as catalyst and characterization by infrared spectra, nuclear magnetic resonance spectra, mass spectra and elemental analyses. The structures of 4e and meso 4b were determined by X-ray crystallography. The association constants of the compounds with various metal ions were
以4-(二甲基氨基)吡啶为催化剂,合成了一系列新的杂大环二酰胺-酯化合物(4a-4z,6a-6b),并通过红外光谱,核磁共振谱,质谱和元素分析进行了表征。通过X射线晶体学测定4e和内消旋 4b的结构。化合物与各种金属离子的缔合常数通过紫外可见光谱滴定法测定,并显示出对某些金属离子的选择性识别。
