    摘要:
    我们已经描述了合成芳基吡啶的三芳基吡啶的CH芳基化/环转化策略,这形成了硫肽抗生素的核心结构。这种合成方法很容易通过两阶段方法以区域选择性方式得到2,3,6-三芳基吡啶:CH芳基化(镍催化的脱羰Suzuki-Miyaura交叉偶联和脱羰CH偶联以合成2 ,4-二芳基恶唑)和环转化([4 + 2] 2,4-二芳基恶唑与(杂)芳基丙烯酸的环加成)。为了展示这些方法,我们已经完成了硫肽抗生素GE2270和支链霉菌素的正式合成。

    A Practical Approach to the Synthesis of 2,4-Disubstituted Oxazoles from Amino Acids
    摘要:
    [GRAPHICS]A new sequence for the synthesis of various 2,4-disubstituted oxazoles from alpha-amino acids is reported. The method is shown to be general and incorporates the reagent combination, triphenylphosphine/hexachloroethane, for cyclodehydration of intermediate alpha-acylamino aldehydes. Implementation of this reagent system for the conversion of alpha-acylamino ketones to oxazoles is briefly investigated.

  • Divergent Palladium‐Catalyzed Tandem Reaction of Cyanomethyl Benzoates with Arylboronic Acids: Synthesis of Oxazoles and Isocoumarins
    作者:Ling Dai、Shuling Yu、Wenzhang Xiong、Zhongyan Chen、Tong Xu、Yinlin Shao、Jiuxi Chen
    DOI:10.1002/adsc.202000125
    日期:2020.4.27
    A palladium‐catalyzed tandem reaction of cyanomethyl benzoates with arylboronic acids has been achieved. Substitution at the 2‐position of cyanomethyl benzoates was found to be crucial for the selective synthesis of oxazoles and isocoumarins. Cyanomethyl benzoates afforded 2,4‐diaryloxazoles as products, while 2‐benzoyl‐substituted cyanomethyl benzoates delivered 3‐benzoyl‐4‐aryl‐isocoumarins selectively
    已实现了基甲基苯甲酸酯与芳基硼酸催化串联反应。已发现在基甲基苯甲酸酯的2位取代对于选择合成恶唑和异香豆素至关重要。苯甲酸甲酯提供了2,4-二芳基恶唑,而2-苯甲酰基取代的基甲基苯甲酸酯则选择性地提供了3-苯甲酰基-4-芳基-异香豆素。此外,讨论了基甲基苯甲酸酯与芳基硼酸选择性反应的可能机理。
  • Synthesis of 2,4-Disubstituted Oxazoles by a Copper-Catalyzed [3+2] Annulation/Olefination Cascade between Amides and IIII/PV Hybrid Ylides
    作者:Zhaofeng Wang、Xingchen Ye
    DOI:10.1055/a-2185-0673
    日期:——
    We report a novel and efficient method for oxazole synthesis through a copper-catalyzed [3+2] annulation/olefination cascade between readily available iodonium–phosphonium hybrid ylides and amides. An unprecedented α-phosphonium Cu carbenoid acts as the key intermediate. This method features excellent regioselectivity with mild reaction conditions and a broad substrate scope. Its synthetic utility
    我们报告了一种新颖有效的恶唑合成方法,通过催化的[3+2]环化/烯化级联在容易获得的杂化叶立德和酰胺之间进行。前所未有的 α-胡萝卜素充当关键中间体。该方法具有优异的区域选择性、反应条件温和、底物范围广等特点。其合成效用通过其在后期功能化和基于恶唑基序的手性配体的快速合成中的应用得到证明。
  • Manganese‐catalyzed Dehydrogenation of Amido Alcohols with Liberation of Hydrogen for the Synthesis of Oxazoles
    作者:Max Leinert、Torsten Irrgang、Rhett Kempe
    DOI:10.1002/cctc.202301042
    日期:2023.11.22
    The synthesis of oxazoles from abundantly and diversely available and inexpensive starting materials such as esters and amino alcohols is reported. Our reaction proceeds via liberation of hydrogen and a molecular manganese catalyst mediates it most efficiently. All oxazole derivatives reported, except the screening substrate and an application, are novel compounds indicating the difficulties associated
    据报道,由丰富多样且廉价的起始材料(例如酯和基醇)合成恶唑。我们的反应通过释放氢气进行,而分子催化剂最有效地介导它。除筛选底物和应用外,所有报道的恶唑生物都是新化合物,表明选择性芳基化和烷基化恶唑的合成存在困难。
