One pot synthesis of amidoalkyl naphthols by reaction of aromatic aldehydes, 2-naphthol and amide/urea using nano-sulfated zirconia as a catalyst is reported. The reaction was carried out under solvent-free conditions. The method gave good yields of amidoalkyl naphthols in short reaction time. The catalyst is recycled for five consecutive times without loss of activity. (C) 2011 Abbas Zali. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
