Three novel nitrogen-containing macrolides have been synthesized by esterification. All of them have been characterized by infrared (IR), elemental analysis, mass spectra (MS), and 1H NMR spectroscopy, and their crystal structures were determined by single-crystal X-ray diffraction. The preparation methods and the intermolecular associations based on C-H・・・O hydrogen bonds and π- π stacking interactions are discussed.
三种新型含氮大环内酯已通过酯化合成。它们均通过红外(IR)、元素分析、质谱(MS)和1H核磁共振波谱进行了表征,并且它们的晶体结构是通过单晶X射线衍射确定的。讨论了基于C-H···O氢键和π-π堆积相互作用的制备方法和分子间关联。
