The invention relates to a process for the production of perbenzylated 1-O-glycosides of general formula I or salts thereof
1
in which
sugar
1
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 C
1
-C
30
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.
该发明涉及一种生产通式I的过苄基化1-O-糖苷或其盐的方法,其中糖1是在1-OH位置上官能化的单糖,R代表苄基,n为2、3或4,X代表—COO—或—NH—,L代表直链、支链、饱和或不饱和的C1-C30碳链,该碳链可以选择性地被基团中断或取代。根据该发明的方法从经济起始材料开始,提供良好的产率,并允许在工业规模上生产具有1-O官能化侧链的过苄基化糖类。
