Description
Summary:A simple, efficient and green procedure for synthesis 1-(benzothiazolylamino)methyl-2-naphthol derivatives via one-pot three-component condensation of aromatic aldehydes, β-naphthol and 2-aminobenzothiazole has been studied by using a novel hybrid catalyst NH3(CH2)5NH3BiCl5 under solvent-free conditions at 100 °C. This method has several advantages such as operational simplicity, recyclability of catalyst, easy workup, short reaction time and excellent yields. [Display omitted] •It exhibited excellent catalytic activity for the synthesis of substituted 1- (benzothiazolylamino) methyl-2-naphthol.•The synthetized products are acquired with very good outputs and very short time of reactions.•The heterogeneous catalyst was easily separated from the reaction mixture.•The catalyst was several times recycled without obvious loss of its catalytic activity.
