Process for the production of perbenzylated 1-O-glycosides

摘要

The invention relates to a process for the production of perbenzylated 1-O-glycosides of general formula I or salts thereof in which sugar¹ is a monosaccharide that is functionalized in 1-OH-position, R represents benzyl, n means 2, 3 or 4, X means -COO- or -NH- and L means a straight-chain, branched, saturated or unsaturated C₁-C₃₀ carbon chain, which optionally is interrupted or substituted by groups. The process according to the invention starts from economical starting materials, provides good yields and allows the production of perbenzylated saccharides with 1-O-functionalized side chains on an industrial scale.
