CA 2172817

A process for the production of arabinonucleotides of general formula I Image (I), in which X represents a hydrogen atom or a fluorine atom, is described, which is characterized in that an arabinonucleoside of general formula II Image (II), in which X has the above-mentioned meaning, is fermented in the presence of an aryl phosphate of general formula III Image (III), in which Y symbolizes a hydrogen atom or a nitro group and Z symbolizes two hydrogen atoms or two alkali metal atoms, with a microorganism that is capable of phosphorylating nucleosides.

L'invention concerne un procédé de préparation d'arabinonucléotides de la formule générale (I), dans laquelle X désigne un atome d'hydrogène ou un atome de fluor. Ce procédé se caractérise en ce que l'on fait fermenter un arabinonucléoside de la formule générale (II) dans laquelle X a la notation mentionnée ci-dessus, avec un micro-organisme apte à la phosphorylation de nucléosides en présence d'un phosphate d'aryle de la formule générale (III), dans laquelle Y désigne un atome d'hydrogène ou un groupe nitro et Z désigne deux atomes d'hydrogène ou deux atomes de métal alcalin.
