Condensation of 2,4-di-O-acetyl-3,6-di-O-methyl-a-~glucopyranosyl bromide with either ally1 or benxyl2,4-di-0-methyl-cu+rhamnopyranoside in the presence of mercuric cyanide, followed by 0-deacetylation, gave the title oligosaccharides in excellent yields.
Treatment of benzyl 2-acetamido-2-deoxy-alpha-D-galactopyranoside with 4-methoxybenzaldehyde dimethyl acetal in N,N-dimethylformamide in the presence of 4-toluenesulfonic acid afforded the 4,6-O-(4-methoxybenzylidene) acetal, which was glycosylated with 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosy
Recent years have seen a remarkable surge of interest in the study of U-Lfucosyltransferases. Of these L-fucosyltransferases, the enzyme (143)~a+fucosyltransferase has attracted a great deal of clinical interest as a potential tumor marker. This enzyme catalyzes the transfer of an L-fucosyl group f
