EFFECTIVE SYNTHESIS OF 7-HYDROXYISOFLAVONE O-GLUCOSIDES

An effective procedure for condensing acetobromoglucose with 2,4-dihydroxy phenyl benzyl ketones has been developed.The 2-hydroxy-4-(β-D-tetra-O-acetylglucopyranosyloxy)phenyl benzyl ketones synthesized with yields of 47-69percent have been converted under the action of ethyl orthoformate in pyridine solution into 7-hydroxyisoflavone O-glukosides and these have also been obtained by the glycosylation of 7-hydroxyisoflavone.The advantages and disadvantages of the alternative pathways of the synthesis of 7-hydroxyisoflavone O-glykosides are discussed.
