A new and efficient synthesis of polysubstituted pyrroles by a sequential one-pot three-component reaction between primary aliphatic amines, active methylene compounds, and 1,2-diaza-1,3-dienes (DDs) is reported. The reactions were performed without catalyst and under solvent-free conditions with complete control of pathway selectivity. Notably, the ready availability of the starting materials and
通过伯脂肪胺,活性亚甲基化合物和1,2-二氮杂-1,3-二烯(DDs)之间的顺序单锅三组分反应,已报道了一种新的高效合成多取代吡咯的方法。反应在没有催化剂的情况下且在无溶剂的条件下进行,并且完全控制了途径的选择性。值得注意的是,原料的易得性以及反应和后处理的高度实用性使该方法成为获得未知的多取代吡咯的有吸引力的补充方法。
