A series of polysubstituted pyrroles were rapidly synthesized in moderate to good yields via catalyst-free one-pot three-component reaction of 1,3-dicarbonyl compounds with primary amines and nitrostyrenes by using liquid-assisted grinding. This protocol provides several advantages over the conventional chemical synthesis, such as simple work-up procedure, wide substrate scope, short reaction time
采用液体辅助研磨,1,3-二羰基化合物与伯胺和硝基苯乙烯的无催化剂一锅三组分反应快速合成了一系列多取代吡咯,收率适中。该协议比传统的化学合成具有几个优点,例如简单的后处理程序、广泛的底物范围、短的反应时间和环境友好性。通过1 H NMR、13 C NMR 和 ESI-MS 研究证实了多取代吡咯的结构。

An efficient and eco-friendly synthesis of functionalized pyrroles using recyclable montmorillonite clay K10 and KSF catalysts has been described. The clay-catalyzed domino four-component coupling (4CC) of amines, aldehydes, 1,3-dicarbonyl compounds and nitroalkanes produced functionalized pyrroles in good yields. The developed methods offers advantages such as operational simplicity, economical, simple
Abstract An environmentally friendly, straightforward, and cheap synthesis of highlysubstitutedfunctionalized pyrrole derivatives via one pot four-component reactions of 1,3-dicarbonyl compounds, amines, aromatic aldehydes, and nitroalkanes have been developed. This methodology provides desired pyrroles in good-to-excellent yields in the presence of Fe (III)-Schiff base/SBA-15 as a heterogeneous
