Ultrasound-promoted synthesis of 1-amidoalkyl-2-naphthols via a three-component condensation of 2-naphthol, ureas/amides, and aldehydes, catalyzed by sulfamic acid under ambient conditions.
A three-component one-pot condensation of 2-naphthol, ureas/amides and aldehydes catalyzed by sulfamic acid, under ultrasound irradiation and ambient conditions gives 1-amidoalkyl-2-naphthols in excellent yield and in short time.
