Abstract

Résumé An easy and convenient synthesis of two new trihydroxyphenacylidentriphenylphosphoran... from phloroglucinal and pyrogallol is described. Some dihydroxyflavones are prepared by acylation of these ylids, intramolecular olefination and saponification of the two remaining ester groups.
