Efficient Synthesis of 3,6-Dideoxy-β-d-arabino-hexopyranosyl-Terminated LacdiNac Glycan Chains of the Trichinella spiralis Parasite
摘要:
The synthesis of a linear trisaccharide epitope of the Trichinella spiralis N-linked glycan, in a form amenable to glycoconjugate formation, is reported. The trisaccharide contains the synthetically challenging LacdiNAc [beta-GalpNAc(1-->4)-beta-GlcpNAc] element, as well as a terminal 3,6-dideoxy-beta-D-arabino-hexopyranose (tyvelose) residue. An orthogonal protection strategy is described, which permits the protection and manipulation of three amino groups present in the disaccharide beta-GalNAc(1-->4)-beta-GlcNAc and the tether used to prepare neoglycoconjugates. The beta-linked dideoxyhexose was generated in excellent yield by the introduction of the dideoxyhexose unit as a beta-D-ribo-hexopyranoside (paratose) followed by an oxidation-reduction sequence to generate the beta-D-arabino configuration in high diastereomeric excess. The required dideoxyhexose donor was synthesized in a series of high-yielding steps from glucose utilizing the p-methoxyphenyl glycoside.
