(±)Lespedezaflavanone D,8,5'-di(γ,γ-dimethylallyl)-5,7,2',4'-tetrahydroxyflavanone,has been synthesized by the condensation of 4,6-dimethoxymethoxy-3-(γ,γ-dimethylallyl)-2-hydroxyacetophenone with 2,4-dimethoxymethoxy-5-(γ,γ-dimethylallyl) benzaldehydc followed by cyclization and demethoxymethylation.
