compounds, but there is a lack of efficient methods for their synthesis. We report a convenient and efficient route to these privileged structures starting from easily accessible 2-substituted pyridines and aryne precursors. A small library of compounds has been synthesized utilizing the developed method, affording variously substituted pyrido[1,2-a]indoles in moderate to good yields.
吡啶并[1,2- a ]吲哚被认为是医学上和药学上重要的化合物,但缺乏有效的合成方法。我们报告了从容易获得的 2-取代吡啶和芳炔前体开始的一种方便有效的途径来获得这些特权结构。使用开发的方法合成了一个小型化合物库,以中等至良好的产率提供各种取代的吡啶并[1,2- a ]吲哚。
