The synthesis and characterization of steroidal hemisuccinate esters derived from pregnanolone, pregnenolone, 3β,19-dihydroxy-androst-5-en-17-one and cholic acid are presented. A combined theoretical-experimental analysis of the conformation and self-assembly of the crystalline samples is carried out with support from single crystal X-ray diffraction experiments and DFT computations, featuring Cremer-Pople
介绍了孕烯醇酮、孕烯醇酮、3β,19-二羟基-androst-5-en-17-one 和胆酸衍生的甾体半琥珀酸酯的合成和表征。在单晶 X 射线衍射实验和 DFT 计算的支持下,对晶体样品的构象和自组装进行了组合的理论-实验分析,具有 Cremer-Pople 环褶皱和分子中原子的量子理论 ( QTAIM)分析揭示了这些分子倾向于形成通过经典和非经典氢键相互作用结合的二聚体和三聚体超分子组装体,其方向性和能量学在晶体结构的简化系统中进行了详细讨论。
