Regioselective protection of N-acetyllactosamine with triphenylmethyl (trityl) and pivaloyl groups afforded the corresponding 3, 2′, 4′-tri- and 2′,4′-dihydroxyl derivatives in a few steps, respectively; these derivatives were used efficiently for the syntheses of the title compounds from N-acetyllactosamine in 46% (7 steps) and 19% (8 steps) overall yields, respectively.
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.
A Novel Method for Constructions of β-D-Mannosidic, 2-Acetamido-2-deoxy-β-D-mannosidic, and 2-Deoxy-β-D-arabino-hexopyranosidic Units from the Bis(triflate) Derivative of β-D-Galactoside

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
