English

a process for the preparation of the active ingredients of formulae i and ii according to claim 1, in which r₁, r₂, r₃, r₄, r₅ and r are as defined in claim 1, characterized in that α- or β-1,4-linked di- or oligosaccharides containing a glucose, fructose or mannose molecule at their reducing end are treated with inorganic or organic bases, the 3-deoxy-d-glyceropentulose (3-dgp) of formula i in which r₁, r₂ and r₃ are a hydrogen atom is isolated from the resulting reaction mixture and, if desired, the 3-dgp is converted in a manner known per se to its glycoside (formula i r₁ = alkyl), diacylglycoside (formula i, r₁ = alkyl, r₂, r₃ = r₄co), dianhydride (formula ii, r = h) or diacyldianhydride (formula ii, r = r₅co).

French

procédé de préparation des substances actives de formule i et ii selon la revendication 1, dans lesquelles r₁, r₂, r₃, r₄, r₅ et r ont les significations données dans la revendication 1, caractérisé en ce que l'on traite des di- ou oligosaccharides à liaisons α- ou β-1,4, qui contiennent à leur extrémité réductrice une molécule de glucose, de fructose ou de mannose, avec des bases inorganiques ou organiques, on isole à partir du mélange réactionnel obtenu le 3-désoxy-d-glycéropentulose (3-dgp) de formule i dans laquelle r₁, r₂ et r₃ représentent un atome d'hydrogène et, si désiré, on transforme de façon connue en soi le 3-dgp en son glycoside (formule i, r₁ = alkyle), diacylglycoside (formule i, r₁ = alkyle, r₂, r₃ = r₄co), dianhydride (formule ii, r = h) ou diacyldianhydride (formule ii, r = r₅co).
