Metal chelates of curcuminoids

Article abstract of DOI:10.1080/00945719809349407

Curcuminoids, a group of structurally related 1.3-dicarbonyl compounds, are the most important physiologically active components present in the traditional herbaceous medicinal plant oriental turmeric (Curcuma longa Linn., Zingiberaceae family). Nickel(II), copper(II), zinc(II) and palladium(II) chelates of synthetic analogues of these 1,7-diaryl-1,6-heptadiene-3,5-diones have been synthesized. UV, IR, ¹H and ¹³C NMR and mass spectral data of the ML₂ complexes clearly indicate that the metal ion replaced the enol proton with the formation of a stable six-membered metal chelate ring involving the dicarbonyl function.
