Abstract

The naturally occurring polyphenolic compounds, valoneic and woodfordinic acid dilactones, were synthesized through the classical Ullmann coupling reaction as the key step. To prepare the diaryl ether component, the Ullmann condensation method was applied using the corresponding phenol and arylbromide.
