Amino acid fluoride for glycopeptide synthesis
Ito, Yukishige,Gerz, Manfred,Nakahara, Yoshiaki
, p. 1039 - 1042 (2000)
The formation of N-glycosidic linkage between N-acetylglucosamine (GlcNAc) and asparagine (Asn) was effected using aspartic acid γ-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 p-methoxybenzyl assisted stereoselective β- mannosylation as the key transformation.
