Trityl chloride (TrCl), efficiently catalyzes the one-pot multi-component condensation of β-naphthol with aromatic aldehydes and amides/thioamides/ carbamates such as acetamide, benzamide, nicotinamide, thioacetamide, and methylcarbamate under solvent-free and neutral conditions to afford 1-amido-alkyl-2-naphthols, 1-thioamido-alkyl-2-naphthols, and 1-carbamato-alkyl-2-naphthols in high yields and very short reaction times. Mechanistically, it is interesting that trityl chloride through the in situ generation of trityl carbocation with inherent instability is efficient as a reusable homogeneous organocatalyst in neutral media.

β-cyclodextrin-butane sulfonic acid is reported to be an efficient catalyst for the one-pot synthesis of 1-amidoalkyl-2-naphthols by the multicomponent condensation of aromatic aldehydes, β-naphthol and amides under solvent-free conditions. The present methodology offers several advantages such as shorter reaction time, mild reaction conditions, a simple operational procedure and use of a recyclable catalyst.

Saccharin sulfonic acid (SaSA) is used as a highly efficient and recyclable catalyst for the one-pot multicomponent condensation of 2-naphthol with arylaldehydes and amides (thioamides or alkyl carbamates) under green, mild (70 °C), and solvent-free conditions. In this reaction, 1-amidoalkyl-2- naphthols, 1-thioamidoalkyl-2-naphthols, 1-carbamatoalkyl-2-naphthols, bis(1-amidoalkyl-2-naphthol)s, and bis(1-carbamatoalkyl-2-naphthol)s are produced in high to excellent yields and in relatively short reaction times.
