1-Carbamatoalkyl-2-naphthol derivatives were obtained from one-pot three-component condensation of 2-naphthol, aldehydes, and carbamates catalyzed by copper benzenesulfonate under thermal solvent-free conditions. The effects of amount of catalyst, reaction temperature and solvent on the products yields were investigated. Experimental results showed that only 2 mol% copper benzenesulfoante was enough to induce the conversion. After reaction, catalyst could be recycled four times without distinct loss of catalytic activity. The structures of all products were characterized by 1H NMR, 13C NMR, IR, MS techniques and elemental analysis. A mechanism to rationalize the reaction was proposed.

Key words: carbamatoalkyl naphthols, metal benzenesulfonate, multicomponent reactions, solvent-free condition, Lewis acids
