An efficient, environmentally friendly procedure for the synthesis of amidoalkyl naphthols through the one-pot, three-component reaction of β-naphthol, aryl aldehydes, and acetamide in the presence of a carbon-based solid acid under thermal solvent-free conditions is described. The beneficial features of this new synthetic approach include short reaction time, high yields, clean reaction profiles, and a simple work-up procedure. Furthermore, the catalyst can be readily recycled and reused four times without obvious significant loss of activity. The structure of the catalyst was confirmed by Fourier transform infrared spectroscopy, N2 adsorption/desorption analysis, and X-ray diffraction.
Graphical AbstractAn efficient method for the synthesis of amidoalkyl naphthols via the solvent-free, one-pot, three-component reaction of β-naphthol, aryl aldehydes and acetamide in the presence of a carbon-based solid acid (CBSA) as a reusable heterogeneous catalyst is described. The structure of the catalyst was confirmed by FT-IR, BET and XRD techniques.Figure optionsDownload full-size imageDownload as PowerPoint slide
