Abstract
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.
