A series of nine novel 3-tetrazolylmethyl-azepino[4,5-b]indol-4-ones were prepared in moderate to good overall yields in only two reaction steps. The first step consisted of a one-pot sequential process of an Ugi-azide multicomponent reaction, N-acylation and SN2 to give the xanthates. The second step was an intramolecular cyclization under free radical conditions. Also, their binding modes have been modelled using docking techniques.
我们只用了两个反应步骤就制备出了一系列九种新型 3-四唑甲基氮杂环庚并[4,5-b]吲哚-4-酮,总收率中等至良好。第一步包括乌基氮杂环多组分反应、N-酰化和 SN2 的一锅顺序反应过程,从而得到黄原酸盐。第二步是在自由基条件下进行分子内环化。此外,还利用对接技术对它们的结合模式进行了建模。
