An efficient and direct protocol for the preparation of amidoalkylnaphthols employing a multi-component, one-pot condensation reaction of 2-naphthol, aromatic aldehydes and acetamide or benzamide in the presence of graphite supported perchloric acid under solvent-free conditions is described. The thermal solvent-free procedure offers advantages such as simple work-up, shorter reaction times and higher product yields, and the catalyst exhibited remarkable reactivity and can be recycled.

Mesoporous silica nanoparticles are efficientlyfunctionalized with homopiperazine sulfamic acid. The resulting MSNs-HPZ-SO3H is employed as a nanocatalyst in one-potsynthesis of 1-amidoalkyl-2-naphthols, through three-component condensation reaction of aromatic aldehydes, amides/urea and β-naphthol, under thermal solvent-free conditions. Characterizations of the catalyst are carried out using XRD
