• 論文の詳細を見る

• Benzyl 3,3', 4', 6'-tetra-O-benzoyl-β-di-N-acetylchitobioside (8) was prepared in 5 steps from 3,3', 4', 6'-tetra-O-acetyl-1,6-anhydro-β-di-N-acetylchitobiose [S. Oguri and S. Tejima, Chem. Pharm. Bull., 28,3184 (1980)] by the following series of reactions ; de-O-acetylation, benzoylation, acetolysis of the 1,6-anhydro-β-ring, benzyl glycosidation via oxazoline, and selective de-O-acetylation. Reaction of 8 with 2,3,4-tri-O-benzyl-α-L-fucopyranosyl bromide by a bromide ion-catalyzed reaction afforded benzyl 3,3', 4', 6'-tetra-O-benzoyl-6-O-(2", 3", 4"-tri-O-benzyl-α-L-fucopyranosyl)-β-di-N-acetylchitobioside (10) in 83.4% yield. After removal of the protecting groups of 10,6-O-α-L-fucopyranosyl-di-N-acetyl chitobiose (11) was obtained as needles. ^<13>C-NMR spectra data for 11 are presented.
