Synthesis of 2-Acetamido-2-deoxy-4-O-β-D-galactopyranosyl-D-glucopyranose (N-Acethyllactosamine) Derivatives

In order to provide useful key intermediates for synthesises of complex oligosaccharides, anomeric 1,2',3',4',6,6'-hexa-O-acetyl-N-acetyllactosamines (8:α, and 9:β) and the corresponding 3-O-benzyl ethers (5:α, and 6:β) were synthesized.Condensation of 1,6-anhydro-3-O-benzyl-β-N-acetylglucosamine with acetobromogalactose by a conventional Koenigs-Knorr procedure, followed by selective acetolysis of the 1,6-anhydro-β-linkage, provided 5 and 6.Debenzylation of 5 and 6 gave 8 and 9, respectively.Keywords - Koenigs-Knorr synthesis; 1,6-anhydro-3-O-benzyl-β-N-acetylglucosamine; 1,6-anhydro-β-N-acetyllactosamine derivative; anomeric octaacetyllactosamine; anomeric heptaacetyllactosamine; anomeric 3-O-benzyl-heptaaetyllactosamine
