SYNTHESE DE DIHYDROXY PHENACYLIDENE TRIPHENYLPHOSPHORANES NOUVEAUX PRECURSEURS DE COMPOSES FLAVONOIDES : SYNTHESE D'HYDROXY-6 ET HYDROXY-7 CHROMONES.

The synthesis of two new dihydroxy phenacylidene triphenylphosphoranes from 2,4-dibenzoyloxy and 2,5-dibenzoyloxy acetophenones is described.By acylation of the hydroxyl groups of these ylides, intramolecular olefination of the ester carbonyl group and hydrolysis of the second ester group, some 6-hydroxy and 7-hydroxy chromones are prepared with good yields.
