SYNTHESIS OF METHYL DERIVATIVES OF URONIC ACIDS. I. SYNTHESIS OF METHYL (METHYL Α-D-GALACTOPYRANOSID)URONATE AND ITS 2-, 3-, AND 4-O-METHYL ETHERS

Alternative unidirectional methods for synthesizing methyl (methyl α-D-galactopyranosid)uronate and its mono-O-methyl ethers by the oxidation (with CrO3-H2SO4-acetone) of the corresponding methyl O-benzyl-O-methyl-α-D-galactopyranosides having unsubstituted 6-OH groups to the corresponding methyl O-benzyl-O-methyl-α-D-galactouronic acids followed by esterification with CH2N2 and the catalytic hydrogenolysis of the benzyl groups are proposed.
