  Synthesis of Kojidextrins and Their Protein Conjugates. Incidence of Steric Mismatch in Oligosaccharide Synthesis

  摘要：

  Kojidextrins are biologically important oligosaccharides that are involved in many physiological processes including protein glycosylation and bacterial growth. As part of our project to explore the role kojidextrins may play in bacterial pathogenesis, here we report Synthetic routes to kojibiose (54), -triose (58), -tetraose (64), and -pentaose (69) equipped with alpha-linked (hydrazinocarbonyl)-pentyl aglycon, using linear and convergent strategies. In the search for a rapid convergent strategy for the construction of extended kojidextrins, four kojibiose donors (1-4) were synthesized that contain acyl- and ether-type protecting groups in various ratios. These were tested to probe the influence of diverse protecting group assemblies on their glycosyl donor ability. Attempted condensation of these donors with kojitriose and -tetraose accepters failed to give the desired products apparently because of steric mismatch between the donor and the acceptor moieties. A one-pot procedure was developed for the covalent attachment of the synthetic saccharides through their hydrazido group to human serum albumin (HSA) using Tietze's squarate method to give neoglycoproteins containing up to 28 saccharide units per HSA.

  A novel flexible assembly strategy is described for the modular synthesis of heparin and heparan sulfates. The reported strategy uses monomeric building blocks to construct the oligosaccharide chain to attain a maximum degree of flexibility. In the assembly, 1-hydroxyl glucosazido- and 1-thio uronic acid donors are combined in a sequential glycosylation protocol using sulfonium triflate activator systems

• Strict Stereocontrol by 2,4-<i>O</i>-Di-<i>tert</i>-butylsilylene Group on β-Glucuronylations

  Strict beta-controlled glucuronylations without classical neighboring-group participation were achieved by the assistance of a 2,4-O-di-tert-butylsilylene group. Comparison of activation conditions and conformational analysis indicated that the strict beta-selectivity was achieved by steric hindrance of the 2,4-O-di-tert-butylsilylene group and not by complex glycosyl intermediates.
• Synthesis of benzyl protected β-d-GlcA-(1→2)-α-d-Man thioglycoside building blocks for construction of Cryptococcus neoformans capsular polysaccharide structures

  In a project targeting the synthesis of large oligosaccharide structures corresponding to the Cryptococcus neoformans GXM capsular polysaccharide, an easy access to thiodisaccharide building blocks comprising a beta-linked glucuronic acid moiety and a 6-O-acetyl group was required. Several pathways to such building blocks have been investigated, addressing the problem of constructing a beta-linked glucuronic acid residue protected with groups that are orthogonal to a primary acetyl group. Two efficient routes have been developed, one using benzoylated glucosyl donors to form the beta-linkage followed by a change of protecting groups to benzyls and subsequent introduction of the carboxyl function and the acetyl group. The second route explored the possibility to achieve beta-selectivity using glucuronyl donors without acyl protecting groups. BF3- etherate promoted glycosylations with benzyl (2,3,4-tri-O-benzyl-alpha-D-glucupyranosyl)uronate trichloroacetimidate in the presence of nitrile solvents and at low temperatures reproducibly gave good yields of disaccharides with high beta-selectivity. Furthermore, the use of recently reported glucuronyl thioglycoside donors protected with a cyclic 2,4-silylene acetal was found to represent another efficient and completely beta-selective way to desired disaccharide building blocks.
