Abstract
  • Laccases from different sources have been used, for the first time, for the selective oxidation of the stilbenic phytoalexin transresveratrol (3,5,40-trihydroxystilbene, 1a) on a preparative scale. Specifically, the enzymes from Myceliophtora thermophyla and from Trametes pubescens gave the dehydrodimer 2a in 31 and 18% isolated yields, respectively. These results compare favorably with the reported data for the chemically catalyzed dimerization of 1a (18% yields). The antioxidant properties of 2a have also been investigated. (literal)
