5-[2-(4-Acetyloxyphenyl)ethenyl]benzene-1,3-diyl diacetate
Abstract
The title compound, C20H18O6, was prepared from resveratrol {systematic name: 5-[(E)-2-(4-hydroxyphenyl)ethenyl]benzene-1,3-diol}, which can be isolated from grapes, through triacetylation with using acetic anhydride in pyridine. The two benzene rings are approximately coplanar, making a dihedral angle of 6.64 (14)°, and the three acetoxy group are located on the same side of the plane. The skeleton of the compound resembles a table with three legs. In the crystal, molecules 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.
