1 - fluoro - production manner of gurikuron Acid and its salt and that kind of new 1 - fluoro - gurikuron Acid and its salt

摘要

A process for producing 1-fluoro-glycuronic acids which may contain protected amino groups and their salts, in which glycopyranosylfluorides of mono or oligo-saccharides with at least one primary OH function are oxidised in aqueous solution in the pH region of 6 to 9, using oxygen as the oxidising agent, in the presence of a catalyst containing at least one metal of the platinum group, the resultant 1-fluoro-glycuronic acids are at least partially neutralised. The invention also relates to compounds of general formula (I), in which M is hydrogen or a cation, especially an alkaline metal, X is oxygen or NH, mutually independently, where with X = oxygen, R is hydrogen or a glycosidically bonded monosaccharide and where with X = NH, R is an acyl, alkyl, aryl or aralkyl protective group radical with up to 10 C atoms, but where only one of the RX groups stands for anything other than OH.
