  • Synthesis of a group of diosgenyl saponins with combined use of glycosyl trichloroacetimidate and thioglycoside donors
    作者:Hai Yu、Biao Yu、Xiangyang Wu、Yongzheng Hui、Xiuwen Han
    DOI:10.1039/a909218h
    日期:——
    With the combined use of glycosyl trichloroacetimidates and thioglycosides, a group of natural diosgenyl saponins (1–6) are efficiently synthesized, in either a stepwise or a ‘one-pot’ manner. The trichloroacetimidate is employed as an efficient temporary hydroxy protecting group in glycosylation with the glycosyl trichloroacetimidate. The intermolecular alkylthio-group transfer is demonstrated to be a common side-reaction during glycosylation with thioglycosides.
    通过结合使用糖基三亚胺代糖苷,一系列天然薯蓣皂苷元的皂苷(1-6)被高效地合成,无论是逐步合成还是“一锅法”合成。三亚胺作为糖基化反应中糖基三亚胺的临时羟基保护组,表现出高效性。代糖苷参与的糖基化反应中,分子的烷基转移被证实是一种常见的副反应。
  • Synthesis of a hexasaccharide fragment of group E streptococci polysaccharide and the tetrasaccharide repeating unit of E. coli O7:K98:H6

    Syntheses of a hexasaccharide, the dimer of the repeating unit of the group E streptococci polysaccharide, and a tetrasaccharide, the repeating unit of the E. coli 07:K98:H6, were achieved by constructing alternate alpha-L-(l --> 2)- and alpha-L-(1 --> 3)linked L-rhamnopyranose backbones and substituting with beta-linked D-glucopyranose side chains for the former, and a D-gluco-pyranosyluronate branch for the latter, respectively, at O-2 of the L-rhamnose ring.
