    摘要:
    The structure of a new biologically active delta-lactone, produced by Seiridium unicome, was determined to be (2S,3R,5S)-(-)-2,3-dihydroxytetradecan-5-olide. The relative configuration was elucidated from NMR experiments. The synthesis of the enantiomer from D-glucose revealed the absolute configuration. The total synthesis of the natural form was also achieved from (R)-malic acid. (C) 1998 Elsevier Science Ltd. All rights reserved.

  • Oxidative Decarboxylation as a Route to Ketene Acetals:  Assignment of Relative and Absolute Stereochemistry to the Fungal Metabolite Benesudon by Total Synthesis
    作者:Derrick L. J. Clive、Minaruzzaman

    日期:2007.12.1
    The unusual ketene acetal benesudon, which is a bioactive fungal metabolite, was synthesized from d-glucose by a route involving radical cyclization to form the five-membered ring and oxidative decarboxylation to generate the key central double bond. The originally suggested stereochemistry for the quaternary center C(5) must be revised, as both possibilities were prepared and a comparison with an

  • Regioselective Sulfonylation/Acylation of Carbohydrates Catalyzed by FeCl<sub>3</sub> Combined with Benzoyltrifluoroacetone and Its Mechanism Study
    作者:Jian Lv、Jia-Jia Zhu、Yu Liu、Hai Dong
    DOI:10.1021/acs.joc.9b03128
    日期:2020.3.6
    A catalytic amount of FeCl3 combined with benzoyl trifluoroacetone (Hbtfa) (FeCl3/Hbtfa = 1/2) was used to catalyze sulfonylation/acylation of diols and polyols using diisopropylethylamine (DIPEA) or potassium carbonate (K2CO3) as a base. The catalytic system exhibited high catalytic activity, leading to excellent isolated yields of sulfonylation/acylation products with high regioselectivities. Mechanism
    使用二异丙基乙胺(DIPEA)或碳酸钾(K2CO3)作为碱,将催化量的FeCl3与苯甲酰基三氟丙酮(Hbtfa)(FeCl3 / Hbtfa = 1/2)结合用于催化二醇和多元醇的磺酰化/酰化。该催化体系表现出高催化活性,导致具有高区域选择性的磺酰化/酰化产物的优异分离产率。机理研究表明,FeCl3最初在碱性条件下于室温下于溶剂乙腈中以两倍的Hbtfa量形成[Fe(btfa)3](btfa =苯甲酰基三氟丙酮酸酯)。然后,在碱的存在下,Fe(btfa)3和底物的两个羟基形成五元或六元环中间体。环状中间体和磺酰化试剂之间的随后反应导致底物的选择性磺酰化。所有关键中间体均在高分辨率质谱分析中捕获,因此首次证明了这种机理。
