The solvent‐free synthesis of substituted pyrroles in high yields using chitosan as a green, recyclable, and reusable catalyst has been described. This multicomponent protocol includes the reaction of aldehydes, amines, 1,3‐dicarbonyl compounds, and nitromethane. The use of a green, biodegradable, environmentally benign, and available catalyst along with its high activity in a four‐component reaction (4CR) makes this method an efficient alternative route to substituted pyrroles. The catalyst can be recycled and reused for several times, without a considerable loss in its activity.

壳聚糖作为有机催化剂的一锅多组分取代吡咯合成

已经描述了使用壳聚糖作为绿色，可回收和可重复使用的催化剂无溶剂合成高取代度吡咯的方法。该多组分方案包括醛，胺，1,3-二羰基化合物和硝基甲烷的反应。使用绿色，可生物降解，对环境无害且可用的催化剂，以及在四组分反应（4CR）中具有高活性，使该方法成为取代吡咯的有效替代途径。该催化剂可以循环使用多次，而不会损失其活性。
