PREPARATION AND CHARACTERIZATION OF β-D-FRUCTOFURANOSYL O-(α-D-GALACTOPYRANOSYL URONIC ACID)-(1->6)-O-α-D-GLUCOPYRANOSIDE AND O-(α-D-GALACTOPYRANOSYL URONIC ACID)-(1->6)-D-GLUCOSE

β-D-Fructofuranosyl O-(α-D-galactopyranosyl uronic acid)-(1->6)-O-α-D-glucopyranoside (3) was prepared by treating raffinose with D-galactose oxidase, followed by hypoiodite oxidation of the resulting aldehyde.Mild acid hydrolysis of 3 gave O-(α-D-galactopyranosyl uronic acid)-(1->6)-D-glucose.

Stereoselective Syntheses of α-Glucuronides Using Dehydrative Glycosylation

Methyl and benzyl 2,3,4-tri-O-benzyl-D-glucopyranuronates, prepared from D-glucurono-6,3-lactone, afforded selectively the corresponding α-glucopyranosiduronates by the aid of the condensing reagent system composed of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, and triethylamine. Using this method, O-α-D-glucopyranuronosyl-(1→3)-O-α-L-arabinofuranosyl- (1→3)-D-xylopyranose, one of the minimal component units in the structure of plantago-mucilage A from the seeds of Plantago asiatica Linne constituting a Chinese medicine : chegianzi [HU~P].

Formation of Uronic Acid by Galactose Oxidase

The C-6 hydroxymethyl group of methyl D-galactopyranoside and oligosaccharides containing D-galactopyranosyl residues were found to be oxidized with oxygen by galactose oxidase to the corresponding carboxyl group via an aldehyde intermediate.

SYNTHESIS OF PART OF THE ANTIGENIC REPEATING-UNIT OF Streptococcus pneumoniae TYPE II

Condensation of methyl 4-O-acetyl-3-O-(2,3,4-tri-O-acetyl-α-L-rhamnopyranosyl)-α-L-rhamnopyranoside with 2,3,4,6-tetra-O-benzyl-α-D-glucopyranosyl chloride gave a mixture of methyl O--(12)-O-(2,3,
