An atom-efficient and environment-friendly approach for the synthesis of amidoalkyl naphthols (4a-x) via multicomponent one-pot reaction of 2-naphthol (1), aromatic aldehyde (2) and amide (3) catalyzed by P2O5 has been developed. The present approach offers several advantages such as reduced reaction times, moderate temperature, higher yields, eco-friendly reaction condition, easy purification and economic availability of the catalyst.
