Description
Summary:A new allyl derivative of curcumin containing three allyl groups (1<i>E</i>,6<i>E</i>)-4-allyl-1,7-bis(4′-allyloxy-3′-methoxyphenyl)hepta-1,6-diene-3,5-dione was synthesized by the reaction of curcumin with the excess of allyl bromide in the presence of K<sub>2</sub>CO<sub>3</sub> in acetone under reflux. The triple-allylated curcumin was characterized by <sup>1</sup>H and <sup>13</sup>C-NMR spectroscopy and single-crystal X-ray diffraction analysis.
