Abstract

[MediaObject not available: see fulltext.]The paper describes a convenient method for the preparation of N-substituted 2,5-dimethylpyrroles using edible sweetener saccharin. Various heterocyclic and aromatic hydrazides have been converted to their corresponding Paal-Knorr pyrroles at room temperature in methanol with saccharin as a green catalyst. Saccharin can be recycled for the next two runs without apparent loss in its activity. Here we propose a method which is speedy, proficient, and ecologically safe.
