Abstract

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.
