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,
means —O—, —S—, —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 enlarged scale.
本发明涉及一种生产通式I的1-O-苄基化糖苷或其盐的过程,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,代表-O、S、COO或NH,L代表直链、支链、饱和或不饱和的C1-C30碳链,该碳链可以被中断或取代。本发明的过程从经济实惠的起始材料开始,提供良好的产量,并允许在扩大规模上生产1-O官能化侧链的苄基化糖苷。
