  Synthesis of differentially protected ribitol derivatives from 3,4-O-benzylidene-d-ribono-1,5-lactone

  摘要：

  Several differentially protected ribitol derivatives were synthesised using 3,4-O-benzylidene-D-ribono-1,5-lactone as versatile starting compounds for oligosaccharide synthesis. The obtained ribitol derivatives allow the regiospecific coupling of glycosyl donors to either of the hydroxyl groups of ribitol and can be applied for the preparation of polyhydroxylated compounds.
