SIMPLE AND EFFECTIVE SYNTHESIS OF ISOFLAVONES AND 3-ARYLOXYCHROMONES

Conditions have been developed for an effective synthesis of 7-hydroxy- and 5,7-dihydroxyisoflavones and also of 3-aryloxy-7-hydroxychromones.The disadvantages and advantages of alternative pathways for the synthesis of these compounds are discussed.The proposed method of synthesis permits considerable simplification of the preparation of compounds of these series.
