A novel method for constructing β-D-mannosidic, 2-acetamido-2-deoxy-β-D-mannosidic and 2-deoxy-D-arabino-hexopyranosidic units from the bis(triflate) derivative of β-D-galactoside

An efficient construction of the β-D-mannosidic, 2-acetamido-2-deoxy-β-D-mannosidic, 2-deoxy-2-fluoro-β-D-mannosidic, and 2-deoxy-β-D-arabino-hexopyranosidic units from the same intermediate, 2-4-bis(O-trifluoromethylsulfonyl) derivative of β-D-galactoside, was achieved in good yields in a stepwise inversion at C-4 and C-2 by using cesium acetate, n-Bu4NN3, n-Bu4NF, and n-Bu4NBH4. A convenient and practical protection of β-D-mannoside to the straightforward synthesis of antennary oligosaccharides was also achieved by using cesium trifluoroacetate.

The useful constructions of β-D-mannosidic, 2-acetamido-2-deoxy-β-D-mannosidic, and 2-deoxy-β-D-arabino-hexopyranosidic units from the same intermediate, 2,4-bis(O-trifluoromethanesulfonyl) derivative of β-D-galactoside, were achieved in a stepwise invers
