Abstract
An improved, simple, and facile synthesis of amidoalkyl naphthols by employing three-component one-pot condensation reaction of β-naphthol, aromatic aldehydes, and amides in ionic liquids using ytterbium triflate as a mild Lewis acid catalyst is described. Advantageously, amidoalkyl naphthols were obtained in high yield under eco-friendly, economical, and non-corrosive conditions, and the catalyst was recycled.
