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.
