| titleOfInvention | METHOD OF OBTAINING 6,8-IODINE-3,7,3 ', 4'-TETRAMETOXY-QUERCETINE AND 8-IODO-3-7-3', 4'-TETRAMETOXY-QUERCETINE FROM QUERCETINE |
| abstract | method of obtaining 6,8-iod0-3, 7,3 ', 4'-tetramethoxy quercetin and 8-iod0-3, 7,3', 4'-tetramethoxy quercetin from quercetin. The present invention relates to the provision of tetramethoxy substituted iodine derivatives of quercetin, a commercially available low cost abundant natural flavonoid. iodinated derivatives obtained in a simple, direct and environmentally friendly procedure using inexpensive and affordable reagents, resulting in high value-added products useful as raw materials (synthesis substrates) in obtaining biflavonoids and other synthesis products. Specifically, the present invention reports the synthesis of 6,8-diiodine and 8-iodo-3,7,3 ', 4'-tetramethoxyquercetin, two novel products in the patent literature and quite promising as activated derivatives for reactions. nucleophilic substitution and various couplings, resulting in new series of compounds with potential biological activity. |
