摘要:Process for regiospecific preparation of new 3-hydroxypyridine-4(1H)-one derivatives starting from monosaccharides or itols of general formula:in which R represents a radical, either saturated or not, branched or not, having carbon-atom groups, and having hetero-atoms or not, and Sub represents a saccharide derivative or an itol, either cyclic not, protected or not, the hydrocarbon skeleton of which is bound to the nitrogen atom of the pyridinone either directly or by the intermediary of a spacing group. The present invention is characterized in that the process comprises a first step of protection of the 3-hydroxy group of the pyranone derivative, a second basocatalyzed step of substitution of the intracyclic oxygen atom of the pyranone by the nitrogen atom of the amine function of the amino monosaccharide or amino itol, and a third step of de-protection of the 3-OH group of the pyridinone cycle and possibly of the OH groups of the glucide or itol residue. It also regards the products obtained by this process, as well as their applications, namely as medicaments for the treatment of toxic overloads of FeIII.
