plot analysis of their molecular geometry, demonstrated their larger size and increased conformational flexibility as compared to the parent heterocycles and confirmed their potential utility as building blocks for lead optimization programs.
设计并合成了4个基于3-((杂)环丁基)氮杂环丁烷的哌啶,哌嗪和吗啉等位异构体,合成量达到了克级。合成序列的关键步骤包括将N保护的2-(氮杂环丁烷-3-基)丙烷-1,3-二醇或相应的1,3-二溴化物环化。对所得产物进行X射线衍射研究,然后对其分子几何结构进行出口向量图分析,证明了与母体杂环相比,它们的尺寸更大,构象柔韧性更高,并证实了其潜在的实用性,可作为潜在客户优化程序的基础。
