  • 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
    过氧化物(1)与三甲基甲硅烷三氟甲磺酸盐(TMSOTf)结合提供了强大的亲促进剂体系,能够活化不同的糖苷。在存在不同的糖基受体的情况下,武装和解除武装的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.
