Nitration of 1-aryl(or 1-benzyl)pyrroles 1, 2 and 7 has provided the corresponding 2- and 3-nitropyrroles 3 and 5, 4 and 6, and 8 and 9 in a 1:2 ratio. Reductive cyclisation of 3 and 8, gave pyrrolo[1,2-a]quinazolines 11 and 12, and pyrrolo[1,2-b][2.4]benzodiazepine 13, respectively. A conformational study of 5 in the solid and liquid state using X-ray diffraction analysis, molecular dynamics calculations
1-芳基(或1-苄基)的硝化吡咯1,2和7提供了相应的2-和3-硝基吡咯3和5,4和6,和8和9中以1:2的比例。3和8的还原环化,得到吡咯并[1,2-a]喹唑啉11和12,和吡咯并[1,2-b] [2。4 ]分别为苯二氮卓13。描述了使用X射线衍射分析,分子动力学计算和NMR光谱对固态和液态5进行的构象研究。
