used to assign configurations to the three stereoisomers of benzilosazone is briefly reviewed. The configuration of the stable isomer is shown to be Z,Z by single crystal X-ray diffraction analysis, instead of E,E as previously reported. This assignment, together with physical measurements and spectroscopic (NMR and UV) data, allows the establishment of the configuration of all isomers. Computational
的1先前用来分配配置来benzilosazone的三种立体异构体CH类NMR参数的简要回顾。通过单晶X射线衍射分析,稳定异构体的构型显示为Z,Z,而不是先前报道的E,E。这种分配,加上物理测量和光谱数据(NMR和UV),可以确定所有异构体的构型。采用计算方法来阐明异构体的构型与其1 H NMR之间的关系,从而解释了先前错误分配的起因。
