Thermalrearrangement of the natural neoflavanoid, (±)-obtusaquinol, yields (±)-obtusafuran. In aqueous acid media obtusaquinol, latifolin and related phenolic 3,3-diarylpropenes rearrange to the isomeric 2-cinnamylphenols. The acid-catalyzed transformations involve initial elimination of a cinnamyl cation. 3-Cinnamylflavans are formed as minor products in these reactions.
