  • Thioperoxide-Mediated Activation of Thioglycoside Donors
    作者:Hongwen He、Xiangming Zhu
    DOI:10.1021/ol501211z
    日期:2014.6.6
    trimethylsilyl trifluoromethanesulfonate (TMSOTf) provides a powerful thiophilic promoter system, capable of activating different thioglycosides. Both armed and disarmed thioglycosides were activated effectively in the presence of different glycosyl acceptors, giving glycosidation products in high to excellent yields. A plausible activation pathway was also proposed and supported by isolating side-products
    硫过氧化物(1)与三甲基甲硅烷基三氟甲磺酸盐(TMSOTf)结合提供了强大的亲硫促进剂体系,能够活化不同的硫糖苷。在存在不同的糖基受体的情况下,武装和解除武装的硫代糖苷都被有效地激活,从而以高到极好的收率得到糖苷化产物。还提出了一条可行的活化途径,并通过分离副产物三氟甲基苯基二硫化物(CF 3 SSPh)和烯烃(42)予以支持。
  • Exploring and Exploiting the Reactivity of Glucuronic Acid Donors
    作者:Ana-Rae de Jong、Bas Hagen、Vincent van der Ark、Herman S. Overkleeft、Jeroen D. C. Codée、Gijsbert A. Van der Marel
    DOI:10.1021/jo201586r
    日期:2012.1.6
    The relative reactivity of glucuronic acid esters was established in a series of competition experiments, in which two thioglucoside and/or thioglucuronic acid ester donors competed for a limited amount of activator (NIS-TfOH). Although glucuronic add esters are often considered to be of very low reactivity, the series of competition reactions revealed that the reactivity of the glucuronic acid esters studied is sufficient to provide productive glycosylation reactions. The latter is illustrated in the synthesis of two Streptococcus pneumoniae trisaccharides, in which the applicability of the two similarly protected frame-shifted thiociisaccharide donors, Glc-GlcA and GlcA-Glc, were compared. The Glc-GlcA disaccharide, featuring the glucuronic acid donor moiety, proved to be the most productive in the assembly of a protected S. pneumoniae trisaccharide.
  • Remote Activation of Disarmed Thioglycosides in Latent-Active Glycosylation via Interrupted Pummerer Reaction

    yields. Meanwhile, observation of thiosulfinate, thiosulfonate, and disulfide suggested that the leaving group was activated via an interrupted Pummerer reaction. The disarmed SPSB thioglycosyl donors could be selectively activated in the presence of various thioglycosides with remote activation mode. Finally, two natural hepatoprotective glycosides, Leonoside E and Leonuriside B, were efficiently synthesized
    S-糖苷,即 S-2-(2-丙硫基) 苄基 (SPTB) 糖苷,通过简单的选择性氧化被转化为相应的氧化糖基供体 S-2-(2-丙基亚磺酰基) 苄基 (SPSB) 糖苷。用三氟甲磺酸酐处理解除武装的 SPSB 供体和各种受体,以良好到极好的产率提供所需的糖苷。同时,对硫代亚磺酸盐、硫代磺酸盐和二硫化物的观察表明离去基团是通过中断的普默勒反应激活的。解除武装的 SPSB 硫糖基供体可以在各种硫糖苷的存在下以远程激活模式被选择性地激活。最后,使用这种新开发的方法以收敛的方式有效地合成了两种天然的保肝糖苷,Leonoside E 和 Leonuriside B。
