Abstract
In this work, efficient, mild, and eco-friendly procedure of 1-aminoalkyl-2-phenol/Betti base from one-pot three-component condensations of aldehyde, phenol, and morpholine in the presence of sulfated polyborate catalyst, under a solvent-free condition at 100 °C, is described. The key advantages of the present method are short reaction time, high yields, aqueous work-up procedure, low cost, stable, reusable catalyst, and solvent-free reaction conditions.
