  Orthogonal glycosylation strategy in synthesis of extended blood group B determinant

  摘要：

  The orthogonal glycosylation strategy was applied for the synthesis of extended blood type B determinant (2) of a novel glycolipid 1. Key features in the synthesis are 1) four monosaccharide units were synthesized as either glycosyl fluoride or thioglycoside to be engaged to the orthogonal glycosylation strategy and 2) all necessary manipulations were completed at the monosaccharide level, therefore, manipulations during the elongation of sugar chain were minimized.

  An object of the present invention is to provide a method for efficiently chemically synthesizing biomolecules including a nucleotide (nucleic acid), a peptide (protein), or a sugar chain, as representative examples. The present invention provides a method of solid-phase synthesis of sugar chain(s) for synthesizing multiple types of sugar chains in at least one sugar chain synthesis reaction system comprising multiple types of monosaccharide units, which is characterized in that it comprises changing the temperature in the sugar chain synthesis reaction system depending on the temperature rising rate that has been determined based on a decrease in side reaction(s) in the reaction system as an indicator.

  examined using N,N-diethylaminosulfur trifluoride (DAST). Although the reaction proceeded without N-bromosuccinimide (NBS), in some cases it was found that the electrophilicity of the Vilsmeier-type electrophilic sulfinium cation species was not sufficient for the activation of certain less-reactive thioglycosides. Here, we report the results of fluorination reactions of a series of monosaccharides using

• Synthesis of a library of fucopyranosyl-galactopyranosides consisting of a complete set of anomeric configurations and linkage positions

  A library composed of a complete set of fucopyranosyl-galactopyranosides was synthesized. A perbenzylated phenylthio fucopyranoside and a series of tri-O-benzyl-galactopyranosyl fluorides having single hydroxyl groups at the 2-, 3-, 4-, and 6-positions were used as the glycosyl donor and glycosyl acceptors, respectively. The chosen set of functionalities at the anomeric centers enabled rapid access to the oligosaccharides based on chemoselective activation. The first coupling reaction was achieved by the action of dimethyl(methylthio)sulfonium trifluoromethanesulfonate (DMTST). The resulting disaccharide fluoride was readily activated by hafnocene bistrifluoromethanesulfonate [Cp2Hf(OTf)(2)] and glycosidated with n-octanol. (c) 2006 Elsevier Ltd. All rights reserved.
