A robust route to 2,4-disubstituted pyrrole heterocycles relying upon a cascade reaction is reported. The reaction benefits from operational simplicity: it is air and moisture tolerant and is performed at ambient temperature. Control over the reaction conditions provides ready access to isopyrroles, 2,3,4-trisubstituted pyrroles, and 3-substituted pyrollidin-2-ones.
报告了一种依赖于级联反应的合成 2,4-二取代吡咯杂环的稳健方法。该反应具有操作简单的优点:它对空气和水分具有耐受性,可以在环境温度下进行。通过控制反应条件,可以轻松获得异吡咯、2,3,4-三取代吡咯和 3-取代吡咯烷-2-酮。
