SYNTHESIS OF 7-O-β-D-GLUCOPYRANOSIDES OF ISOFLAVONES AND THEIR HETEROCYCLIC ANALOGUES

Article abstract of DOI:10.1007/BF00630111

The products of the interaction of α-acetobromoglucose with 2,4,5-trihydroxyphenyl benzyl ketone and 2,4-dihydroxyphenyl 4'-hydroxybenzyl ketone and also with their heterocyclic analogues, which are present completely or partially in the enolic form, have been investigated.It has been shown that in this reaction a tetra-O-acetylglucosyl residue is added at the 4-OH hydroxy group of the phenyl residue of the ketone.The compounds obtained have been converted into isoflavone 7-O-glucosides by the action of the Vilsmeier reagent or acetoformic anhydride.
