    Synthesis of valiolamine and its N-substituted derivatives AO-128, validoxylamine G, and validamycin G via branched-chain inosose derivatives
    摘要:
    Novel synthetic routes to valiolamine (1a) and N-substituted valiolamine derivatives via branched-chain inosose derivatives are described. (1S)-(1(OH),2,4/1,3)-2,3,4-Tri-O-benzyl-1-C-[(benzyloxy)methyl]-5-oxo-1,2,3,4-cyclohexanetetrol (3), a branched-chain inosose derivative prepared from D-glucose, 2 has been converted into 1a via the ketoxime 7 followed by hydrogenation. N-Substituted valiolamine derivatives having strong alpha-D-glucosidase inhibitory activity have been synthesized by the direct reductive amination of the branched-chain inosose derivative 3 with an appropriate amino compound to construct the N-substituent moiety, followed by removal of the O-benzyl protecting group. The stereoselective preparation of two representative derivatives, N-[2-hydroxy-1-(hydroxymethyl)ethyl]valiolamine (2a, AO-128)3 and N-[1R,2R)-2-hydroxyclohexyl]valiolamine (2b)3 is described. Application of branched-chain inosose derivatives 3 and 23 to the total synthesis of natural N-substituted valiolamine derivatives validoxylamine G (5a) and validamycin G (6a) is also described.

    日期:2005.9.1
    We have utilized our recently developed in vitro assay to address two key questions in the design of small-molecule cholesterol absorption inhibitors using ezetimibe, the only drug yet approved for the inhibition of cholesterol absorption in the small intestine, as a starting point: (1) the role of glycosylation and (2) the importance of the beta-lactam scaffold of ezetimibe for inhibitory activity
    我们已经利用我们最近开发的体外测定法来解决使用依泽替米贝设计小分子胆固醇吸收抑制剂的两个关键问题,依泽替米贝是唯一尚未批准的抑制小肠胆固醇吸收的药物,作为出发点:(1 )糖基化的作用,以及(2)依泽替米贝的β-内酰胺支架对于抑制活性的重要性。合成了多种依泽替米贝的不可水解酚类糖苷,并使用刷状缘膜囊泡测定法证明是胆固醇吸收的活性抑制剂。类似的氮杂环丁烷提供了体外使用各种抑制剂的途径,这表明依泽替米贝的β-内酰胺仅用作适当地定位所需取代基的环骨架。
  • Self‐Promoted Glycosylation for the Synthesis of β‐ <i>N</i> ‐Glycosyl Sulfonyl Amides
    作者:Patrycja Mała、Christian Marcus Pedersen
    DOI:10.1002/ejoc.202100808
    日期:2021.11.8
    Glycosyl sulfonyl amides are synthesized in a self-promoted N-glycosylation with high β-selectivity and in high yields. Armed and disarmed glycosyl donors of different size and with different protective groups react smoothly with sulfonyl amides, such as protected asparagine derivatives. Influence of solvents, concentration, temperature and stoichiometry is studied.

    Dehydrative glycosylation using 2,3,4,6-tetra-O-benzyl-D-glucopyranose was carried out by the use of a condensing reagent system composed of diethylaminosulfur trifluoride (DAST), tin(II) triflate, tetrabutylammonium perchlorate, and triethylamine.
