“…The interest in curcumin [(1E,6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)hepta-1,6-diene-3,5-dione] [1,2,3,4,5,6,7,8,9] has prompted many structural studies on this β-diketone tautomerism [10,11,12,13,14] as well as on the synthesis and structural studies of hemicurcuminoids, compounds resulting from the replacement of one styryl branch of curcumin (2-methoxy-4-vinylphenol) by a simpler group, for instance, a phenyl group [11,15].…”
