    An Improved Catalyst System for the Pd-Catalyzed Fluorination of (Hetero)Aryl Triflates
    摘要:
    The stable Pd(0) species [(1,5-cyclooctadiene)(L.Pd)(2)] (L = AdBrettPhos) has been prepared and successfully evaluated as a precatalyst for the fluorination of aryl triflates derived from biologically active and heteroaryl phenols, challenging substrates for our previously reported catalyst system. Additionally, this precatalyst activates at room temperature under neutral conditions, generates 1,5-cyclooctadiene as the only byproduct, and leads to overall cleaner reaction profiles.

  • A General, Multimetallic Cross-Ullmann Biheteroaryl Synthesis from Heteroaryl Halides and Heteroaryl Triflates
    作者:Kai Kang、Nathan L. Loud、Tarah A. DiBenedetto、Daniel J. Weix

    medicine and materials science, the synthesis of biheteroaryls by cross-coupling remains challenging. We describe here a new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered, and fused heteroaryl bromides and chlorides, as well as aryl triflates derived from heterocyclic phenols,
    尽管它们对医学和材料科学很重要,但通过交叉偶联合成双杂芳基仍然具有挑战性。我们在这里描述了一种新的、通用的双杂芳基方法:杂芳基卤化物与三氟甲磺酸酯的 Ni 和 Pd 催化的多金属交叉 Ullmann 偶联。一系列 5 元、6 元和稠合杂芳基溴化物和氯化物,以及衍生自杂环酚的芳基三氟甲磺酸酯,被证明是该反应中可行的底物(62 个示例,平均产率为 63 ± 17%)。这种方法对双杂芳基的普遍性在 10 μmol 规模的 96 孔板格式中得到进一步证明。一组 96 种可能的产品在一组条件下提供了 >90% 的命中率。此外,可以使用配体、添加剂和还原剂的单个“工具箱板”快速优化低产率组合。

    organic synthesis and materials science. We describe herein a palladium-catalyzed dienylation of aryl, heteroaryl, and vinyl triflates, nonaflates and iodides that were previously identified as recalcitrant substrates for the sulfolene-mediated catalytic dienylation. The method has now been successfully expanded to C-O and C-I dienylation, demonstrating broad scope with respect to sulfonates, iodides
    共轭二烯和多烯是天然产物的中心结构图案,也是有机合成和材料科学中的关键合成中间体。我们在本文中描述了芳基,杂芳基和乙烯基三氟甲磺酸酯,壬二酸酯和碘化物的钯催化的二烯基化,这些化合物先前已被确定为环丁二烯介导的催化二烯基化的顽固底物。该方法现已成功扩展到CO和CI二烯基化,在磺酸盐,碘化物和亚砜方面具有广阔的应用前景。反应进行时具有很高的区域选择性和立体选择性,并且效率受到碱性添加剂的强烈影响,因此系统地研究了其对反应性能的影响。
  • <i>Z</i>-Selective Dienylation Enables Stereodivergent Construction of Dienes and Unravels a Ligand-Driven Mechanistic Dichotomy

    bonds because it allows for control of stereoselectivity and efficiency of formation of each double bond. A conceptually distinct dienylation approach entails a stereoselective appendage of a four-carbon unit, shortcutting diene synthesis. Dienylation with sulfolene provided a direct route to E-dienes, but the synthesis of substantially more challenging Z-dienes remained elusive. Here, we report that
    由于它们在药物化学、有机合成和材料科学中的关键作用,开发用于构建共轭二烯和多烯的立体选择性和高效反应一直处于有机化学的前沿。共轭二烯和多烯的合成通常通过依次安装单个 C=C 键以多步方式完成,因为它允许控制立体选择性和每个双键的形成效率。概念上不同的二烯化方法需要立体选择性附加四碳单元,从而缩短二烯合成。环丁砜的二烯化提供了直接生成E-二烯的途径,但合成更具挑战性的Z-二烯仍然难以捉摸。在这里,我们报告说,现在可以通过简单地调整配体来实现高度Z选择性二烯化,从而能够从一种试剂和一步中立体发散合成E-和Z-二烯。对E和Z选择性二烯化的详细机理研究提供了对两种催化体系不同行为的深入了解,并揭示了催化活性钯膦配合物的相对稳定性的差异对二烯化的立体化学结果有重大影响。
  • Oxidative Addition Complexes as Precatalysts for Cross-Coupling Reactions Requiring Extremely Bulky Biarylphosphine Ligands
    作者:Bryan T. Ingoglia、Stephen L. Buchwald

    日期:2017.6.2
    addition complexes (OACs) as effective precatalysts for C–N, C–O, and C–F cross-coupling reactions with a variety of (hetero)arenes. These complexes offer a convenient alternative to previously developed classes of precatalysts, particularly in the case of the bulkiest biarylphosphine ligands, for which palladacycle-based precatalysts do not readily form. The precatalysts described herein are easily prepared
    在本报告中,我们描述了基于钯的氧化加成配合物(OAC)作为C–N,C–O和C–F与多种(杂)芳烃交叉偶联反应的有效预催化剂的应用。这些配合物为先前开发的类别的预催化剂提供了一种方便的替代方法,特别是在体积最大的联芳基膦配体的情况下,基于这些化合物不容易形成基于Palladacycle的预催化剂。本文所述的预催化剂易于制备并且对于在空气中长期储存稳定。
  • Development of a Method for the <i>N</i>-Arylation of Amino Acid Esters with Aryl Triflates
    作者:Sandra M. King、Stephen L. Buchwald
    DOI:10.1021/acs.orglett.6b02082
    日期:2016.8.19
    N-arylation of amino acid esters with aryl triflates is described. Both α- and β-amino acid esters, including methyl, tert-butyl, and benzyl esters, are viable substrates. Reaction optimization was carried out by design of experiment (DOE) analysis using JMP software. The mild reaction conditions, which use t-BuBrettPhos Pd G3 or G4 precatalyst, result in minimal racemization of the amino acid ester. This method
    描述了用芳基三氟甲磺酸酯对氨基酸酯进行N-芳基化的一般方法。α-和β-氨基酸酯,包括甲基,叔丁基和苄基酯,都是可行的底物。使用JMP软件通过设计实验(DOE)分析进行反应优化。使用t -BuBrettPhos Pd G3或G4预催化剂的温和反应条件导致氨基酸酯的外消旋作用最小。该方法是t -BuBrettPhos Pd G4预催化剂的首次合成应用。机理研究表明,所观察到的对映体过量腐蚀是由于氨基酸酯原料的消旋作用,而不是产物的消旋作用。
