diastereoselective synthesis of an alpha-L-aculose, alpha-L-rhodinose, and beta-D-olivose trisaccharide is described. The key transformations include the palladium-catalyzed glycosylation, Myers' reductive rearrangement, diastereoselective dihydroxylation, and regioselective Mitsunobu inversion. Significant apoptotic antitumor activity was found for this trisaccharide, which has implication for vineomycinB2 and
