SYNTHESIS OF METHYL ETHERS OF METHYL (METHYL α-D-GLUCOPYRANOSID) URONATE
Methyl (methyl α-D-glucopyranoisid)uronate (I) has been obtained by the catalytic oxidation of methyl α-D-glucopyranoside with oxygen in the presence of platinum on carbon with a yield of 31percent.The partial methylation of (I) followed by preparative liquid column chromatography on silica gel has provided a convenient method of obtaining all the methyl ethers of (I) in the individual state.

STRUCTURAL INVESTIGATION OF Klebsiella K-TYPE 4 CAPSULAR POLYSACCHARIDE
The capsular polysaccharide from Klebsiella K4 contains the tetrasaccharide repeating-sequence 3)-α-D-Glcp-(12)-α-D-GlcpA-(13)-α-D-Manp-(13)-β-D-Glcp-(1.P.m.r. spectroscopy and the measurement of optical rotation were used to establish the anomeric linkages in the polysaccharide and in the oligosaccharides derived by partial hydrolysis.The repeating unit also contains one O-acetyl group.
