    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, means —O—, —S—, —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 enlarged scale.
