  摘要：

  Perbenzylated methyl alpha-L-fucopyranosyl-(1-->2)-beta-D-galactopyranosides having a single free OH group at position C-2'. C-3' or C-4' have been synthesized. Methyl 3,4,6-tri-O-benzyl-beta-D-galactopyranoside was glyco-sylated either with phenyl 3,4-di-O-benzyl-2-O-(2-naphthyl)-methyl-, phenyl 2,4-di-O-benzyl-3-O-(2-naphthyl)methyl- or phenyl 2,3-di-O-benzyl-4-O-(2-naphthyl)methyl-1-thio-beta-L-fucopyranoside. The 2-ONAP ether functioned well as a non-participating group. The yields of the glycosylation reactions, promoted by NIS/TfOH, were above 80% and the stereoselectivity was 8:1 to 10:1 in favour of the alpha-anomers. The 2-ONAP ether was obtained by (2-naphthyl)methylation, the 3-ONAP and the 4-ONAP ethers were prepared either by hydrogenolysis of the 3,4-O-(2-naphthyl)methylene acetals of beta-L-fucopyranoside or by tin acetal-mediated alkylations. The latter procedure afforded higher yields. The ONAP ethers from the disaccharides were removed by oxidative cleavage with DDQ. (C) 2004 Elsevier Ltd. All rights reserved.

  Sulfonic acid analogues of N-acetylneuraminic are synthesized from 1-thio-l-fucoside derivatives with the introduction of an azido group at C-4 of the fucose moiety and carbanionic addition onto fully protected lactones. The analogues in the form of methyl glycosides are subjected to a neuraminidase inhibition assay.

  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.
