A series of hydroxystilbenes, analogues of the bioactive phytoalexin resveratrol, were synthesized and submitted to the catalytic action of a laccase from Trametes pubescens in a biphasic system made of ethyl acetate and acetate buffer. Oxidation took place at the 4′-hydroxy (4-hydroxy) position of the hydroxystilbenic moieties, followed by radical-radical coupling dimerization reactions. Most of the
