A convenient and practical protection of β-D-mannoside to the straightforward synthesis of antennary oligosaccharides was also achieved by using cesium trifluoroacetate., Article}, pages = {885--890}, title = {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}, volume = {70}, year = {1997} }
