Abstract Water was a suitable medium for Paal–Knorr pyrrole cyclocondensation. Hexa-2,5-dione was reacted with several aliphatic and aromatic primary amines, affording N-substituted 2,5-dimethyl pyrrole derivatives in good to excellent yields. An efficient, green method using water either as environmentally friendly solvent or catalyst was presented. GRAPHICAL ABSTRACT
摘要 水是 Paal-Knorr 吡咯环缩合反应的合适介质。Hexa-2,5-dione 与几种脂肪族和芳香族伯胺反应,得到 N-取代的 2,5-二甲基吡咯衍生物,产率很好。提出了一种使用水作为环保溶剂或催化剂的高效、绿色方法。图形概要
