Chemo-enzymatic synthesis of new resveratrol-related dimers containing the benzo[b]furan framework and evaluation of their radical scavenger activities

The chemo-enzymatic synthesis and the evaluation of radical scavenger performance of resveratrolrelated
dimers with antioxidative power have been investigated. The dimeric compounds, containing
the benzo[b]furan framework, were prepared via an oxidative dimerization catalyzed by a laccase from
Trametes versicolor, followed by a treatment with the organic oxidant DDQ. This methodology can be
useful for the synthesis of various 2,3-diarylbenzo[b]furans derivates, a class of compound that exhibits
a wide range of biological activities.
