Synthesis of stilbene-fused 2'-hydroxychalcones and flavanones

Bioorg Chem. 2010 Aug;38(4):139-43. doi: 10.1016/j.bioorg.2010.04.001. Epub 2010 Apr 9.


Synthesis of stilbene-fused chalcones and flavanones were successfully completed. Molecules were designed in a way to mimic the structural features of both "stilbene and chalcones" or "stilbene and flavanones" at the same time, and synthesized by three steps. Heck reactions of 3-bromobenzaldehyde with styrene derivatives gave corresponding (E)-stilbenes, which were reacted with acetophenones to furnish stilbene-fused 2'-hydroxychalcones under basic conditions. Finally, intramolecular cyclization reactions were performed to produce stilbene-fused flavanones.
