Abstract

A convenient and efficient procedure is presented for the one‐pot synthesis of N‐substituted pyrroles by condensation of 2,5‐hexandione and amines or diamines in the presence of cross‐linked polystyrene‐supported aluminum chloride (PS/AlCl~3~) as a highly active and reusable heterogeneous Lewis acid catalyst. This polymeric solid acid catalyst is stable and can be easily recovered and reused without appreciable change in its efficiency. © 2010 Wiley Periodicals, Inc.
