of the (acylimino)thiadiazoline derivatives (1−3) as angiotensin II receptor antagonists. The relative stability of the nonbonded 1,5-type S···O interaction was investigated using the X-ray crystallographic analyses and the ab initio MO calculations (HF/3-21G*, 6-31G*, and 6-311+G**) of the simplified model compounds (6, 7, and 9). The concept of mimic-fused bicyclic heterocycles consisting of fairly
在(酰基亚氨基)噻二唑啉衍生物(1-3)作为血管紧张素II受体拮抗剂的晶体结构中,分子内非键合的1,5-型S…O相互作用被识别。使用 X 射线晶体学分析和 ab initio MO 计算(HF/3-21G*、6-31G* 和 6-311+)研究了非键合 1,5 型 S···O 相互作用的相对稳定性G**) 的简化模型化合物(6、7 和 9)。由相当稳定的非键合 S···O 相互作用组成的模拟稠合双环杂环的概念似乎是设计和开发各种药物的有效方法。
