8-tetraazadecalin (TAD) derivatives. Their structure, static and dynamic conformational analysis, isomerization pathways and relative stabilities were studied using 1H-, 13C-, and 15N-NMR techniques. Molecular mechanics calculations were carried out using the MM2 force field and an earlier modified version for NCN containing systems. The peculiar stereoelectronic features of the CNCNC moieties in the TAD systems
我们提出了一些已知的和新的1,4,5,8-四氮杂cal呤(TAD)衍生物的多学科研究。使用1 H-,13 C-和15 N-NMR技术研究了它们的结构,静态和动态构象分析,异构化途径和相对稳定性。使用MM2力场和包含NfieldCN的系统的早期修改版本进行了分子力学计算。强调了TAD系统中CNCNC部分的独特立体电子特征。
