An efficient green protocol for the preparation of amidoalkyl naphthols, employing a three-component one-pot condensation reaction of beta-naphthol, aromatic aldehyde, amides or urea in the presence of montmorillonite K10 clay under solvent free conditions has been described. The present procedure offers advantages such as shorter reaction time (<2 h), simple workup, excellent yields, recovery and reusability of catalyst. (c) 2007 Elsevier B.V. All rights reserved.
