anilino nitrogen atoms is described. These derivatives show characteristic differences in the 1H-NMR spectra compared with the unsubstituted parent compound. These differences are used to determine structure-conformation relationships of this type of compounds. The conclusions drawn from the 1H-NMR spectra in this respect are supported by X-ray crystallographic data and by 1H-NMR data of conformationally
描述了在苯胺氮原子上烷基化或酰化的2,6-双-苯胺基-3-硝基吡啶的合成。与未取代的母体化合物相比,这些衍生物在1H-NMR光谱中显示出特征差异。这些差异用于确定这类化合物的结构-构象关系。在这方面从1 H-NMR谱得出的结论得到X射线晶体学数据和构象受限的类似物的1 H-NMR数据的支持。初步研究表明,这些关系原则上可以扩展到其他二芳基胺。
