A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 14215-68-0, Name is N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide, molecular formula is C8H15NO6. In a Article£¬once mentioned of 14215-68-0, name: N-((2S,3R,4R,5R,6R)-2,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3-yl)acetamide
SYNTHESIS OF 2-ACETAMIDO-4-O-(2-ACETAMIDO-2-DEOXY-beta-D-GLUCOPYRANOSYL)-2-DEOXY-6-O-(alpha-L-FUCOPYRANOSYL)-D-GLUCOPYRANOSE (6-O-alpha-L-FUCOPYRANOSYL-DI-N-ACETYLCHITOBIOSE)
Benzyl 3,3′,4′,6′-tetra-O-benzoyl-beta-di-N-acetylchitobioside (8) was prepared in 5 steps from 3,3′,4′,6′-tetra-O-acetyl-1,6-anhydro-beta-di-N-acetylchitobiose by the following series of reactions; de-O-acetylation, benzoylation, acetolysis of the 1,6-anhydro-beta-ring, benzyl glycosidation via oxazoline, and selective de-O-acetylation.Reaction of 8 with 2,3,4-tri-O-benzyl-alpha-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-alpha-L-fucopyranosyl)-beta-di-N-acetylchitobioside (10) in 83.4 percent yield.After removal of the protecting groups of 10,6-O-alpha-L-fucopyranosyl-di-N-acetyl chitobiose (11) was obtained as needles. (13)C-NMR spectra data for 11 are presented.Keywords: – synthesis; 6-O-alpha-L-fucopyranosyl-di-N-acetylchitobiose; 1,6-anhydro-di-N-acetylchitobiose derivative; oxazoline glycosidation method; benzyl di-N-acetyl-chitobioside derivative; bromide ion-catalyzed glycosidation; selective de-O-acetylation; (13)C-NMR
