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.
本发明涉及一种用于生产一般式I或其盐的过苯基化1-O-糖苷的工艺,其中糖1是在1-OH位置上被官能化的单糖,R代表苯甲基,n为2、3或4,代表-O-、-S-、-COO-或-NH-,L代表直链、分支、饱和或不饱和的C1-C30碳链,可选地被中断或取代。本发明的工艺从经济实惠的原料开始,提供良好的产量,并允许在扩大规模的情况下生产具有1-O功能化侧链的过苯基化糖苷。
