Molybdophosphoric Acid: An Efficient Keggin-type Heteropolyacid Catalyst for the One-pot Three-Component Synthesis of 1-Amidoalkyl-2-naphthols

摘要

A one-pot three-component reaction of 2-naphthol,aldehyde,urea or amide catalyzed by the molybdophosphoric acid (heteropolyacid) to afford 1-amidoalkyl-2-naphthols is described,which is high yield with simple work-up.
