Objective To total synthesize Genistein's derivative 7 -difluoromethoxy -5,4′ -dimethoxy isoflavone. Methods The target compound were synthesized by phloroglucinol and p-methoxy phenylacetonitrile through Hoesch reaction and carbon-adding cyclization to get the isoflavone, then through difluoromethylation and methylation. Results The structures of the target compound and it's intermediates were confirmed by 1H-NMR , the overall yield was 15.6%.Conclusion The process was short in steps, easy to control , low in cost and practice in industrialize.
