  • First Direct Glycosylation of Unprotected Nonreducing Mono- and Disaccharides
    作者:Andreas Steinmann、Julian Thimm、Joachim Thiem
    DOI:10.1002/ejoc.200700504
    日期:2007.11
    glycosyl acceptors is reported by random glycosylation leading to all possible regioisomers. For such systems conventional glycosylation methods such as Koenigs–Knorr glycosylation, Schmidt's trichloroacetimidate glycosylation and reactions employing glycosyl fluoride donors fail entirely. Starting from unprotected nonreducing saccharides, the glycosylation of β-glucosylated and β-galactosylated monosaccharides
    完全无保护的糖基受体的第一个单步随机糖基化方法报告通过随机糖基化导致所有可能的区域异构体。对于此类系统,传统的糖基化方法,例如 Koenigs-Knorr 糖基化、Schmidt 的三氯乙酰亚胺糖基化和使用糖基氟供体的反应完全失败。从未受保护的非还原糖开始,研究了 β-葡萄糖基化和 β-半乳糖基化单糖(Glc、Gal)、对称二糖(例如 α,α-海藻糖)以及不对称二糖(例如蔗糖)的糖基化。检查了碱类型和浓度的影响。生成了几个二糖和三糖文库。所有区域异构体以大致相等的比例形成,用快速柱色谱法实现部分分离。尽管与经典的保护基化学相比,总体产率似乎较低,但这种合成努力可能更胜一筹,尤其是在获得更高的糖类方面。(© Wiley-VCH Verlag GmbH & Co.

  • Desymmetrization of trehalose via regioselective DIBAL reductive ring opening of benzylidene and substituted benzylidene acetals
    作者:Vikram A. Sarpe、Suvarn S. Kulkarni
    DOI:10.1039/c3ob41389f
    日期:——
    Trehalose dibenzylidene and substituted dibenzylidene acetals were reductively opened either at O6 or O4 in a regioselective manner by using a DIBAL stock solution prepared in toluene or dichloromethane, respectively, to achieve desymmetrization of the trehalose core. The method was applied to synthesize various biologically important unsymmetrically substituted trehalose glycoconjugates, including
    使用在水中制备的DIBAL储备溶液,以区域选择性的方式在O6或O4处还原海藻糖二苄基和取代的二苄基缩醛。 甲苯 或者 二氯甲烷分别实现海藻糖核心的去对称化。该方法被用于合成各种生物学上重要的不对称取代的海藻糖糖结合物,包括分枝杆菌三糖,4-表位-海藻糖类似物和马拉多脂。
  • Regioselective syntheses of trehalose-containing trisaccharides using various glycohydrolases
    作者:Katsumi Ajisaka、Hiroshi Fujimoto
    DOI:10.1016/0008-6215(90)84264-u
    日期:1990.6
    Two methods were investigated for the enzymic preparation of trehalose-containing trisaccharides. In the first, a solution of saccharides is circulated through an immobilized-glycosidase column and an activated-carbon column connected in series. In the second, two enzymes having different substrate specificities are sequentially used for condensation and subsequent specific hydrolysis. Thus, 3-O-beta-D-, 4-O-beta-D-, and 6-O-beta-D-galactopyranosyl-alpha,alpha-trehalose; 4-O-alpha-D- and 6-O-alpha-D-glucopyranosyl-alpha,alpha-trehalose; and 4-O-beta-D- and 6-O-beta-D-glucopyranosyl-alpha,alpha-trehalose were synthesized stereo- and regio-selectively.
