5-[2-(4-Acetyl-oxyphen-yl)ethen-yl]benzene-1,3-diyl diacetate.

ABSTRACT: The title compound, C(20)H(18)O(6), was prepared from resveratrol {systematic name: 5-[(E)-2-(4-hy-droxy-phen-yl)ethen-yl]ben-z-ene-1,3-diol}, which can be isolated from grapes, through triacetyl-ation with using acetic anhydride in pyridine. The two benzene rings are approximately coplanar, making a dihedral angle of 6.64?(14)°, and the three acet-oxy group are located on the same side of the plane. The skeleton of the compound resembles a table with three legs. In the crystal, mol-ecules are linked via C-H?O interactions, forming inversion dimers. These dimers are further linked via C-H?O interactions, forming a three-dimensional structure.
