Abstract
AbstractA 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/AlCl3) 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.
