A simple synthesis of 2-hydroxylated (E)-stilbenes was accomplished in good yields via oxidative coupling of 2-hydroxystyrenes and arylboronic acids, with Rh(III)-catalyst and Cu(OAc)(2) as oxidant. The antiproliferative evaluation of all the synthesized compounds were assessed on four different human cancer cell lines (Colo-205, MDA-468, HT29, and MGC80-3), and the results showed that several compounds exhibit strong antiproliferative activities (up to IC50 = 35 nM for MGC80-3).

In the crystal structure of the title compound, C18H20O5, all geometric parameters fall within experimental error of the expected values. Analysis of the molecular-packing plots reveals an infinite one-dimensional linear array running parallel to the c axis, formed by an O-H...O intermolecular hydrogen-bonding interaction. The stilbene framework and most of the substituents are approximately coplanar.
