diffractometry determined the molecularstructures of both derivatives. The X-ray results were compared to those obtained by conformational analysis followed by semiempirical methodologies (AM1 and PM3). The theoretical calculations yielded results reproducing the whole three-dimensional (3D) structure of both molecules in a good agreement with X-ray structural analysis. The global structures of the two compounds
摘要 通过香豆素体系(3-氨基香豆素或3-羟基香豆素)连接合成化合物1(4-甲基-N-(香豆素-3-基)苯甲酰胺)和2((香豆素-3-基)-4-甲基苯甲酸酯),分别)到对甲苯甲酰氯。1H 和 13C NMR 和 X 射线衍射测定了两种衍生物的分子结构。将 X 射线结果与通过构象分析和半经验方法(AM1 和 PM3)获得的结果进行比较。理论计算产生的结果再现了两种分子的整个三维 (3D) 结构,与 X 射线结构分析非常吻合。这两种化合物的整体结构在两种研究环境中非常相似,这意味着可以外推气相中的结构测定。化合物1和2之间的比较研究,
