Abstract An efficient, green procedure for the synthesis of 4,4′-(arylmethylene)bis(1H-pyrazol-5-ol) and α-amidoalkyl-β-naphthol’s using biodegradable polymeric catalyst chitosan-SO3H (CTSA), is operationally easy to prepare by mixing chitosan and chlorosulfonic acid. This catalyst displays excellent catalytic activity and reusable for five subsequent reactions without significant loss of catalytic

Antimony(III) acetate was used in the one-pot three-component synthesis of multigram quantities of 1-amidoalkyl-2-naphthols from the condensation between aldehydes, 2-naphthol and acetamide under solvent-free conditions at ambient temperature. The present method has several advantages such as high yields, easy purification, mild reaction conditions, easy work-up, survival of different functional groups

1-Amidoalkyl-2-naphthols were prepared via one-pot multi-component reaction of 2-naphthol, aldehydes, and amides in the presence of nano silica phosphoric acid under solvent-free condition at 80 °C. Short reaction times, high yields, and easy work-up are the advantages of this protocol.
A direct approach for the one-pot preparation of 1-amidoalkyl-2-naphthols via three-component reaction of β-naphthol, aromatic aldehydes, and acetamide in the presence of nano-structured Al2O3 under solvent-free conditions has been developed. Some benefits of this procedure are: recyclability of the catalyst, short reaction time, high yield of the products, environmentally benign procedure, and facile work-up.
