- Abstract
- A trisaccharide, GlcNAcp-beta-(1-->3)-Galp-alpha-(1-->2)-6-deoxy-altroHepp-alpha-(1-->O-propyl, as an O-antigenic repeating unit of C. jejuni serotype 0:23 and 0:36 was synthesized. Coupling of the GlcNPhth-(1-->3)-Gal disaccharide donor with allyl 6-deoxy-altroHep acceptor in the presence of iodonium dicollidine Perchlorate (IDCP) promoter afforded the alpha-galactosidic trisaccharide with high stereoselectivities. Subsequent deacetalation, dephthaloylation, N-acetylation, and hydrogenolytic debenzylation furnished the title compound.
