CLXXVIII.—The methylation of quercetin
Journal of the Chemical Society Transactions
WHEREAS in 1884 Herzig (Monntsh., 5, 72) observed that quercetin could not be completely methylated by means of methyl iodide and alkali, v. Kostanecki and Dreher, as the result of their experiments with the monohydroxyxanthones (Rer., 1893, 26, 76), showed that although the methyl ethers of the 2-, 3-, and 4-compounds could be readily prepared by this method, the 1-hydroxyxanthone in which the hydroxyl is adjacent to the carbonyl group was thus not affected.
