  可按千克规模制备的非对映异构纯氰醇可在一个步骤中有效转化为新型l-艾杜隆酰胺。这种艾杜糖醛酰胺的新区域选择性酰化和亚硝酸戊酯介导的新型温和酰胺水解方法能够实现短时间、可扩展的l-艾杜糖醛酸二乙酸酯 C-4 受体的合成，以及l-艾杜糖醛酸 C-4 受体硫糖苷。描述了将这些有效转化为一系列肝素相关葡萄糖-碘二糖构建块（各种 C-4 保护选项），包括对关键肝素构建块 ido-硫糖苷供体的高效多克访问。1-OAc 二糖通过分化为受体和供体二糖而转化为肝素相关四糖。1,2-二乙酰艾杜糖醛酸甲酯和类似艾杜糖酰胺的X射线和核磁共振数据表明，虽然两者在溶液中均采用1 C 4构象，但艾杜糖醛酸酯在固态时采用4 C 1构象。还报道了新型4 C 1的 X 射线结构-构象锁定双环 1,6-脱水艾糖醛酸内酯以及新型扭曲的4 C 1艾糖醛酸内酯4,6-内酯的 X 射线结构。氘标记还提供了在新型亚硝酸戊酯介导的艾杜糖醛

  A tethered nucleophilic substitution strategy for the stereoselective introduction of axially oriented amino functions on suitably protected gluco- and mannopyranosides is presented. The obtained oxazine is a versatile building block, which after some manipulation, could be used in the construction of highly functionalised oligosaccharides.

• Synthesis of Oligodiaminosaccharides Having α-Glycoside Bonds and Their Interactions with Oligonucleotide Duplexes

  Syntheses of the novel oligodiaminosaccharides, alpha-(1 -> 4)linked-2,6-diamino-2,6-dideoxy-D-glucopyranose oligomers, and their interactions with nucleic acid duplexes DNA-DNA, RNA-RNA, and DNA-RNA are described. Monomers to tetramers of oligodiaminoglucose derivatives having alpha-glycosyl bonds were successfully synthesized using a chain elongation cycle including glycosylation reactions of a 6-phthalimide glycosyl donor. UV melting experiments for a variety of nucleic acid duplexes in the absence and presence of the oligodiaminosaccharides were performed. The synthesized oligodiaminosaccharides exhibited notable thermodynamic stabilization effects on A-type RNA-RNA and DNA-RNA duplexes, whereas B-type DNA-DNA duplexes were not stabilized by the synthesized oligodiaminosaccharides. Among the oligodiaminosaccharides, the tetramer exhibited the highest ability to stabilize A-type duplexes, and the increase in T(m) values induced by the tetramer were higher than those induced by neomycin B and tobramycin, which are known aminoglycosides having ability to bind and stabilize a variety of RNA molecules. CD spectrometry experiments revealed that the oligodiaminosaccharides caused small structural changes in RNA-RNA duplexes, whereas no appreciable changes were observed in the structure of DNA-DNA duplexes. ITC (isothermal titration calorimetry) experiments demonstrated that the amount of heat generated by the interaction between RNA-RNA duplexes and the tetradiaminosaccharides was approximately double that generated by that between DNA-DNA duplexes and the tetradiaminosaccharides. These results strongly suggested the existence of an A-type nucleic acid specific-binding mode of the oligodiaminosaccharides, which bind to these duplexes and cause small structural changes.
