Multicomponent preparation of 1-amidoalkyl-2-naphthols using silica-supported molybdenum oxide (MoO3/SiO2) as a mild and recyclable catalyst

An efficient and direct protocol for the preparation of 1-amidoalkyl-2-naphthols employing a multi-component and one-pot condensation reaction of 2-naphthol, aromatic aldehydes, and acetamide in the presence of MoO 3 /SiO 2 under solvent-free conditions is described. The reaction using a catalyst wa...

Description
Summary:An efficient and direct protocol for the preparation of 1-amidoalkyl-2-naphthols employing a multi-component and one-pot condensation reaction of 2-naphthol, aromatic aldehydes, and acetamide in the presence of MoO 3 /SiO 2 under solvent-free conditions is described. The reaction using a catalyst was carried out under mild condition with very high yields up to 93 %. The present approach of this methodology offers several advantages such as shorter reaction times, good yields, low cost, environmentally benign, milder reaction conditions, easy recovery of catalyst, and reusability.
