  • TMSBr-mediated solvent- and work-up-free synthesis of α-2-deoxyglycosides from glycals
    作者:Mei-Yuan Hsu、Yi-Pei Liu、Sarah Lam、Su-Ching Lin、Cheng-Chung Wang
    DOI:10.3762/bjoc.12.164
    日期:——

    The thio-additions of glycals were efficiently promoted by a stoichiometric amount of trimethylsilyl bromide (TMSBr) to produce S-2-deoxyglycosides under solvent-free conditions in good to excellent yields. In addition, with triphenylphosphine oxide as an additive, the TMSBr-mediated direct glycosylations of glycals with a large range of alcohols were highly α-selective.

    甘露糖醛酸盐的硫加成反应可以在无溶剂条件下高效地通过等物量的溴化三甲基硅(TMSBr)催化产生良好至优异收率的S-2-脱氧糖苷。此外,加入三苯基膦氧化物作为添加剂,TMSBr介导的甘露糖醛酸盐与多种醇类的直接糖基化反应具有高度α-选择性。
  • Formal total synthesis of hemibrevetoxin B by a convergent strategy

    日期:2004.6
    Concise construction of the trans-fused 7/7/6/6 tetracyclic ether part of hemibrevetoxin B (1) was achieved by a convergent strategy based on coupling reaction of an acyl anion equivalent, reductive cyclization of an α,ε-dihydroxyketone, and introduction of a methyl group at the central ring junction by the Nicolaou method. The resultant tetracyclic ether was transformed into the known intermediate
    所述的简明结构的反式-融合hemibrevetoxin B(的7/7/6/6四环醚部分1)通过会聚策略基于酰基阴离子等价物的偶联反应,α的还原性环化,ε-dihydroxyketone实现,并且通过Nicolaou方法在中心环连接处引入甲基。将得到的四环醚转化为已知的中间体,该中间体已经被山本基团转化为1,从而完成了1的正式全合成。
  • Variations on the SnCl4 and CF3CO2Ag-promoted glycosidation of sugar acetates: a direct, versatile and apparently simple method with either α or β stereocontrol
    作者:Jia Lu Xue、Samy Cecioni、Li He、Sébastien Vidal、Jean-Pierre Praly

    contrast, simple alcohols afforded approximately 1:1 mixtures of 2,3,4,6-tetra-O-acetyl, and 3,4,6-tri-O-acetyl 1,2-cis-glycosides due to anomerization and/or acid-catalyzed fragmentation of 1,2-orthoester intermediates. After reacetylation or deacetylation, acetylated or fully deprotected 1,2-cis-glycosides (alpha-D-gluco, alpha-D-galacto) were obtained in approximately 90% yields by a simple and direct
    与SnCl(4)和CF(3)CO(2)Ag的过乙酸糖(D-葡萄糖,D-半乳糖)的糖基化导致产生1,2-顺式或1,2-反式-糖苷,主要取决于使用的酒精。特别地,由酰基保护的糖基供体预期的1,2-反式-糖苷以高收率与共享特定特征(例如庞大,吸电子基团或聚乙氧基基序)的醇形成。相比之下,由于异构化和//,简单的醇可提供约1:1的2,3,4,6-四-O-乙酰基和3,4,6-三-O-乙酰基1,2-顺式-糖苷的混合物或酸催化的1,2-原酸酯中间体的裂解。在重新乙酰化或脱乙酰化之后,通过简单和直接的方法以约90%的产率获得了乙酰化或完全脱保护的1,2-顺式-糖苷(α-D-葡萄糖,α-D-半乳糖)。
  • Ferric chloride, an anomerization catalyst for the preparation of alkyl α-glycopyranosides

    DOI:10.1016/s0040-4039(00)74242-0
    日期:1992.7
    Anhydrous FeCl3 in CH2Cl2 has been found to readily anomerize β-glycopyranosides to their corresponding α-anomers in good yields and selectivities at room temperatures. Acetyl- and benzoyl-protected oxygen sugars yielded the best results.
    已经发现CH 2 Cl 2中的无水FeCl 3可以在室温下以良好的产率和选择性将β-糖吡喃糖苷容易地异构化为其相应的α-端基异构体。乙酰基和苯甲酰基保护的氧糖产生了最好的结果。
