POLYSTYRENE SUPPORTED ALUMINIUM TRIFLATE AS A HETEROGENEOUS CATALYST FOR THE SYNTHESIS OF 1-AMIDOALKYL-2-NAPHTHOLS

Polystyrene supported aluminium triflate (Ps-Al(OTf)3) was prepared from polystyrene supported aluminium chloride (Ps-AlCl3) and triflic acid and used as a heterogeneous Lewis acid catalyst for the synthesis of 1-amidoalkyl-2-naphthols from one-pot multi-component condensation of 2-naphthol with aromatic aldehydes and amides at room temperature.
