Oxyresveratrol and its methylated derivative as coupling precursors were efficiently prepared in four steps, with Wittig reactions and subsequent isomerization reactions as the key steps. The coupling reactions of oxyresveratrol under various oxidative conditions gave a complex and inseparable mixture of coupling products. The oxidative dimerizations of methylated oxyresveratrols catalyzed by horseradish peroxidase-H 2O 2or FeCl 3·6H 2O in an acetone system predominantly produced the 8-5-coupled and 8-10-coupled dihydrobenzofuran-type dimers, respectively. This regioselective biomimetic strategy might be useful in synthesizing other dimeric oxyresveratrol derivatives.

From oxyresveratrol (trans-2,4,3′,5′-tetrahydroxystilbene 1), seven derivatives were prepared, including trans-2-methoxy-4,3′,5′-trihydroxystilbene (2), trans-2,3′-dimethoxy-4,5′-dihydroxystilbene (3), trans-4,3′-dimethoxy-2,5′-dihydroxystilbene (4), tran
