• Resumen

  • The utility of sulfamic acid in One-pot assembling of aromatic aldehydes, aromatic amines and β-keto esters to afford densely functionalized tetrahydropyridines in 70-89% yield has been presented. The advantage of sulfamic acid against other catalysts in terms of yield has been studied. The effect of different solvents on reaction time and yield has also been studied. Easy work up and mild reaction condition are the advantages of the proposed method.
