The molecular structures of N-(o-and p-hydroxybenzyl)cytisine were investigated by NMR spectroscopy, x-ray structure analysis, and molecular modeling. It was found that NMR resonances of the OH and aromatic protons in N-(o-hydroxybenzyl)cytisine were doubled because of the presence of two conformers in solution.
通过核磁共振光谱、X射线结构分析以及分子建模对N-(邻-和对-羟基苄基)
金丝桃素的分子结构进行了研究。研究发现,由于溶液中存在两种构象,N-(邻-羟基苄基)
金丝桃素的羟基和芳香族原子的核磁共振共振频率增加了一倍。
