Conclusions
A number of natural isoflavones and their structural analogs have been synthesized by improved ethyl orthoformate and dimethylformamide methods. It has been possible to use the dimethylformamide method for the first time for the synthesis of 5,7-dihydroxyisoflavones. Two new isoflavones have been synthesized: 7-methoxyisoflavone and 5,7-dihydroxy-3′,4′-dimethoxyisoflavone.
