  • Process for the synthesis of curcumin-related compounds
    Patent number: 5679864
    Abstract: The invention is directed to a process for the synthesis of curcumin and curcumin-related compounds by reacting the enol form of a 2,4-diketone with a monocarbocyclic aldehyde in the presence of an organic amine catalyst. The reactants are dissolved in a highly polar, aprotic organic solvent. The curcumin-related product is recovered in crystalline form by precipitation from the reaction mass and solvent recrystallization.
