R.sub.2 =NHCOR.sub.3, NHCOCH.sub.2 X, NHSO.sub.2 CH.sub.3, N(SO.sub.2 CH.sub.3).sub.2, SO.sub.2 N(CH.sub.3).sub.2, SO.sub.2 NHCH.sub.3, SO.sub.2 NCH.sub.3 CH.sub.2 CH.sub.2 OH, SO.sub.2 NH.sub.2 wherein R.sub.3 is a lower alkyl containing 1 to 4 carbon atoms; and X is NR.sub.4 R.sub.5 or ##STR2## wherein R.sub.4 and R.sub.5 are both independently lower alkyls containing 1 to 4 carbon atoms and ##STR3## is piperidine, pyrrolidine or morpholine. These products can be in the form of pharmaceutically acceptable derivatives such as esters, amides, salts. When R.sub.2 contains an amino function, the product can be in the form of an acid salt.These products are prepared from their methyl esters either by reaction between ##STR4## and paramethoxycarbonylbenzoic acid chloride or by means of derivative I such as R.sub.2 is NH.sub.2.The products of this invention are used in therapy in the prevention and treatment of complications from diabetes or as diuretics.

    摘要: This invention relates to quercetin or fisetin derivatives substituted on the oxygen in the 3 position by groups such as lower alkyl, cycloalkyl, methanesulfonyl or paratoluenesulfonyl.The derivatives substituted by methanesulfonyl or paratoluenesulfonyl are obtained from a 3-O-glycoside whose phenol OH groups are blocked in the form of benzoate, and from which the OH in the 3 position is released by the action of concentrated HCl; this OH is esterified by mesityl chloride or paratoluenesulfonic acid chloride, and the benzoate groups are eliminated by soda treatment. The O derivatives substituted by alkyl or cycloakyl are prepared from a suitably substituted acetonitrile or metadiphenol; the resulting derivative reacts with 3,4-dibenzyloxybenzoic acid and the resulting flavone is debenzylated by hydrogenolysis.The derivatives, object of this invention, are useful in preventive or curative therapy of ocular and nervous complications from diabetes and are also useful as hypolipidemic or hypoglycemic agents.
