SYNTHESES OF METHYL ESTERS OF URONIC ACIDS. IV. SYNTHESIS OF THE 3-O-, 2,3-, 2,4-, AND 3,4-DI-O-, AND 2,3,4-TRI-O-METHYL ETHERS OF METHYL (METHYL α-D-MANNOPYRANOSID)URONATE

The synthesis is described of methyl O-benzyl-O-methyl-α-D-mannopyranosides and their oxidation by chromium trioxide, leading, after catalytic hydrogenolysis, to the 3-O, 2,3-, 2,4-, and 3,4-di-O-, and 2,3,4-tri-O-methyl ethers of methyl (methyl α-D-manno
