  Amino acid fluoride for glycopeptide synthesis

  摘要：

  The formation of N-glycosidic linkage between N-acetylglucosamine (GlcNAc) and asparagine (Asn) was effected using aspartic acid gamma-fluoride in combination with either glycosyl azide or silyl carbamate, by the action of Lindlar catalyst or Bu4NF Further elongation of peptide chain was performed to give pentapeptide. This method was further applied into the synthesis of trisaccharidic asparagine, using beta-methoxybenzyl assisted stereoselective B-mannosylation as the key transformation.

  A general methodology for the efficient formation of N-glycosidic linkage to asparagine (Asn), which, does not require the protection of sugar component hydroxyl groups is described. Aspartic acid fluoride was used in combination with N-allyloxycarbonyl (Alloc) glycosyl amines. Pd(0)-PhSiH3 mediated in situ Alloc removal-coupling was performed in aqueous solution dioxane to give Asn-linked carbohydrates in high yield.

  Various types of protein glycosylation have been identified from prokaryotes. Recent investigations have revealed the presence of N-linked glycoproteins in the pathogenic bacterium, Campylobacter jejuni. The structure of this glycan is unique, consisting of 5 Ga1NAc and 1 G1c, in addition to 2,4-diacetamido-2,4,6-trideoxy-D-glucopyranose (bacillosamine; Bac), which is N-glycosidically linked to the side chain of asparagine (Asn). We synthesized Bac from a 2-azido-2-deoxy-D-galactose derivative, which was further converted to the Asn-linked form. (c) 2006 Published by Elsevier Ltd.
