The novel metabolites (2'S,3'R)-3,10-dihydroxy-9-O-(6'-hydroxy-2'-hydroxymethyldihydrofuran-3-yl)-dibenz--pyran-6-one and its 5',6'-dihydroxy analogue are accompanied in the heartwood of Umtiza listerana by several known flavonoids and the parent 3,9,10-trihydroxydibenz--pyran-6-one.The latter, used for structural elucidation of the complex dibenzo-α-pyrones, was synthesized via a Hurtley condensation.Key Word Index-Umtiza listerana; Leguminosae; heartwood metabolites; (2'S,3'R)-3,10-dihydroxy-9-O-(6'-hydroxy-2'-hydroxymethyldihydrobenzofuran-3-yl)-dibenz--pyran-6-one; (2'S,3'R)-3,10-dihydroxy-9-O-(5',6'-dihydroxy-2'-hydroxymethyldihydrobenzofuran-3-yl)-dibenz--pyran-6-one; 3,9,10-trihydroxydibenz--pyran-6-one; flavonoids; 1H NMR; synthesis.
