Iodine catalyzed preparation of amidoalkyl naphthols in solution and under solvent-free conditions

A one-pot three-component reaction of 2-naphthol, aldehydes and urea or amides has efficiently been carried out in the presence of iodine in dichloroethane at room temperature or under solvent-free conditions at higher temperature to form the corresponding amidoalkyl naphthols in high yields.
