Abstract
A convenient route to the synthesis of 3-aryloxy-7-β-D-glucopyranosyloxy-chromones has been developed which consists in the condensation of α-aryloxy-2, 4-dihydroxyacetophenones with acetobromoglucose and the conversion of the α-hydroxy-2, 4-dihydroxyacetophenone 4-O-glucosides so obtained into the desired 3-aryloxy-7-glucosyloxychromones. Conditions for the effective performance of the latter transformation have been found.
