(Z)-2-acetoxy-3,3′,4′-trimethoxystilbene

The crystal structure determination demonstrates unambiguously that the title compound, 2-[(Z)-3,4-dimethoxyphenylethenyl]-6-methoxypheenyl acetate, C19H20O5, has the Z configuration. The title compound was prepared by decarboxylation of (E)-3-(2-acetoxy-3-methoxyphenyl)-2-(3,4-dimethoxyphenyl)propenoic acid; this compound was in turn obtained by condensation of 2-acetoxy-3-methoxybenzaldehyde with (3,4-dimethoxyphenyl)acetic acid. 1H NMR data for the title compound and the isomeric (E)-2-acetoxy-3,3′,4′-trimethoxystilbene are reported.
