  • <i>S</i>-Benzoxazolyl (SBox) Glycosides in Oligosaccharide Synthesis: Novel Glycosylation Approach to the Synthesis of β-<scp>d</scp>-Glucosides, β-<scp>d</scp>-Galactosides, and α-<scp>d</scp>-Mannosides
    作者:Alexei Demchenko、Medha Kamat、Cristina De Meo

    Per-acetylated and per-benzoylated S-benzoxazolyl (SBox) glycosides have been synthesized and applied to highly efficient 1,2-trans glycosylation. Complete stereoselectivities and remarkably high yields were achieved for the synthesis of β-d-glucosides, β-d-galactosides, and α-d-mannosides. It was also de­monstrated that benzoylated ‘disarmed’ SBox glycosides could be selectively activated in the presence of both armed and disarmed ethyl thioglycosides. Convergent synthesis of the tetra­saccharide β-d-Glc-(1-6)-β-d-Gal-(1-6)-β-d-GlcNAc-(1-6)-α-d-GlcOMe was achieved in three sequential selective glycosylation steps.
    合乙酰化和合苯甲酰化的S-苯并噁唑基(SBox)糖苷已被合成并应用于高效的1,2-反式糖苷化。对β-d-葡萄糖苷、β-d-半乳糖苷和α-d-甘露糖苷的合成实现了完全的立体选择性和显著高的产率。还证明了苯甲酰化的“去活化”SBox糖苷可以在有活化和去活化的乙糖苷同时存在的情况下被选择性激活。成功实现了四糖β-d-Glc-(1-6)-β-d-Gal-(1-6)-β-d-GlcNAc-(1-6)-α-d-GlcOMe的汇聚合成,通过三步连续的选择性糖苷化反应完成。

    pentasaccharide repeating unit of the capsular polysaccharide of Escherichia coli (E. coli) strain applying block [2 + 3] stereoselective glycosylation. A functionalized disaccharide thioglycoside donor prepared using “armed-disarmed” glycosylation concept, was coupled with suitably protected trisaccharide glycosyl acceptor in the presence of a combination of N-iodosuccinimide (NIS) and perchloric acid supported

    report thiouracil-catalyzed α-selective O-glycosylations employing easily accessible glycosyl trichloroacetimidate donors without using any co-catalyst or additive. A variety of alcohol nucleophiles including saccharides, and amino acids with different protecting groups containing glycosyl trichloroacetimidate donors were successfully α-glycosylated using an operationally simple protocol. Moreover, mechanistic
    在此,我们报道了嘧啶催化的α-选择性O-糖基化,使用易于获得的糖基三酰亚胺酯供体,而不使用任何助催化剂或添加剂。使用操作简单的方案成功地将多种醇亲核试剂(包括糖类和具有不同保护基团的含有糖基三酰亚胺酯供体的氨基酸)进行α-糖基化。此外,机理研究表明嘧啶在此糖基化过程中起到布朗斯台德酸/碱催化作用。
  • Glycosyl thioimidates in a highly convergent one-pot strategy for oligosaccharide synthesis
    作者:Papapida Pornsuriyasak、Alexei V. Demchenko
    DOI:10.1016/j.tetasy.2004.11.029
    日期:2005.1
    Application of two classes of thioimidoyl derivatives, S-benzoxazolyl (SBox) and S-thiazolyl (STaz) glycosides to selective activation over thioglycosides is described. These results allowed us to synthesize a tetrasaccharide derivative using a leaving group differentiated one-pot strategy in 73% yield over three sequential glycosylation steps.
