Synthesis of Oligosaccharides Corresponding to the Common Polysaccharide Antigen of Group B Streptococci

To facilitate mapping of the immunodominant region of the common polysaccharide antigen of group B streptococci, tetrasaccharide 1-O--α-rhamnopyranosyl>-D-glucitol (2) was synthesized in a stepwise fasion

LINOMYCIN ANALOGUES. II. CHAIN EXTENSION OF METHYL-6-ALDEHYDO-3,4-O-ISOPROPYLIDENE-1-THIO-β-D-GALACTO-1,5-PYRANOSIDE

Synthesis of methyl 2,3,4,6-tetra-O-acetyl-1-thio-α-D-galactopyranoside and its β-anomer (3 and 4) from the 2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl bromide via the isothiouronium salt in HMPT involved a considerable increase in the proportion of the α-anomer.Deacetylation of (3 and 4) with sodium methoxide yielded 5 and 6 respectively.Conversion of 6 into corresponding 3,4-isopropylidene derivative (7) followed by oxidation with Collin reagent gave the aldehydo-sugar (8) which when reacted with the stabilized phosphorane led in the excellent yield to the Z-unsaturated bromo-sugar (9).
