Abstract: 2-0-Benzyl- and 3-0-benzyl-D-xylose, intermediates bearing nonmigratory
substituents important in carbohydrate syntheses, have been prepared.
Treatment of these with methanolic hydrogen chloride gave crystalline
methyl glycopyranosides, which, upon methylation and removal of the
blocking groups, yielded 2,4-di-O-methyl- and 3,4-di-O-methyl-D-xylopyranose.
