| Abstract: | A novel and efficient
three-component one-pot condensation method has been described for the
synthesis of tetraketones or arylmethylene[bis(3-hydroxy-2-cyclohexene-1-ones)]
using Yb(OTf)3-SiO2 and amine as catalytic system under
solvent free conditions. Tetraketones are obtained in high yield (73-88%). The
application of an eco-friendly, non-corrosive, and reusable catalytic system
makes this method advantageous. |
