Four new compounds 1-4 were obtained from an oxidative coupling reaction of (E)-isorhapontigenin using FeCl3 as oxidant. Their structures and stereochemistry were determined on the basis of spectroscopic evidence [UV, IR, MS, 1H-, 13C-NMR, NOE and 2D NMR], and their possible formation mechanisms were also discussed, respectively.

This study extensively investigated the regioselective oxidative coupling reactions of 5-bromoisorhapontigenin catalyzed by FeCl 3 ·6H 2 O or HRP/H 2 O 2 in different solvent systems and the distinct reductive debromination of the isolated dimeric coupling intermediates. Natural (±)-bisisorhapontigenin A and (±)-lehmbachol A and B were efficiently prepared. (±)-Gnetuhainin I, (±)-gnemontanin E, (±)-7- O -ethylgnetuhainin I, and (±)-gnemontanin F were synthesized for the first time.

The regioselective oxidative cross-coupling reactions of two different stilbene precursors catalyzed by FeCl3 or horseradish peroxidase-H2O2 in acetone solvent produced three dihydrobenzofuran-type heterodimers. The reductive debrominations of these cross-coupled dimers synthesized two heterodimers of resveratrol and isorhapontigenin, an analogue of (±)-scirpusin A and (±)-gnetuhainin Q.
