    摘要:
    The conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to a range of beta-fluoroaryl-alpha,beta-unsaturated esters gave the corresponding beta-amino esters with high diastereoselectivity and in good isolated yields. Sequential treatment of the resultant beta-fluoroaryl-beta-amino esters under optimised hydrogenolysis conditions, followed by ester hydrolysis with 2.0 M aq HCl, provided access to a range of beta-fluoroaryl-beta-amino acids in good yield.

  • Non‐Chelate‐Assisted Palladium‐Catalyzed Aerobic Oxidative Heck Reaction of Fluorobenzenes and Other Arenes: When Does the C−H Activation Need Help?
    作者:Francisco Villalba、Ana C. Albéniz
    DOI:10.1002/adsc.202100677
    日期:2021.10.19
    sole oxidant and no redox mediator. Arenes with either electron-donating or electron-withdrawing groups can be functionalized in this way. Experimental data on the reaction with toluene as the model arene shows that the C−H activation step is turnover limiting and that the ligand structure is crucial to facilitate the reaction, which supports the involvement of the pyridone fragment in the C−H activation
    配体中的吡啶酮片段 [2, 2'-联吡啶]-6(1 H)-one (bipy-6-OH) 使简单芳烃与氧作为唯一氧化剂且无氧化还原介体发生氧化 Heck 反应。具有给电子或吸电子基团的芳烃可以通过这种方式进行功能化。与甲苯作为模型芳烃反应的实验数据表明,CH 活化步骤是周转限制,配体结构对于促进反应至关重要,这支持吡啶酮片段参与 CH 活化步骤。在氟芳烃的情况下,单和 1,2-二氟苯的烯基化需要 bipy-6-OH 的存在。相比之下,这种配体对 1,3-二氟、三、四和五氟苯的烯基化是有害的,这可以仅使用 [Pd(OAc) 2]。这与氟代芳烃的酸度有关,最酸性的酸经历更容易的 CH 活化,因此反应的其他步骤(例如烯烃的配位插入)对于多氟化芳烃在动力学上变得重要。在所有这些反应中,仅使用催化量的钼酸钠作为碱被证明是最佳的。
  • Enantioselective Synthesis of β‐Amino Acid Derivatives Enabled by Ligand‐Controlled Reversal of Hydrocupration Regiochemistry
    作者:Sheng Guo、Jiaqi Zhu、Stephen L. Buchwald
    DOI:10.1002/anie.202007005
    日期:2020.11.16
    A Cu‐catalyzed enantioselective hydroamination of α,β‐unsaturated carbonyl compounds for the synthesis of β‐amino acid derivatives was achieved through ligand‐controlled reversal of the hydrocupration regioselectivity. While the hydrocupration of α,β‐unsaturated carbonyl compounds to form α‐cuprated species has been extensively investigated, we report herein that, in the presence of an appropriate
    铜催化的α,β-不饱和羰基化合物的对映选择性加氢胺化反应合成β-氨基酸衍生物是通过配体控制的氢铜反应区域选择性逆转实现的。虽然已经广泛研究了 α,β-不饱和羰基化合物的氢铜反应形成 α-铜酸盐物质,但我们在本文中报告说,在适当的辅助手性配体存在下,肉桂酸衍生物可以观察到相反的区域化学,导致将铜传递到 β 位。这种铜可以与亲电子胺化试剂 1,2-苯并异恶唑反应,提供富含对映体的 β-氨基酸衍生物,这是合成天然产物和生物活性小分子的重要组成部分。
  • 2-Hydroxy-1,10-phenanthroline vs 1,10-Phenanthroline: Significant Ligand Acceleration Effects in the Palladium-Catalyzed Oxidative Heck Reaction of Arenes
    作者:Cheng-Hao Ying、Shao-Bai Yan、Wei-Liang Duan
    DOI:10.1021/ol4033804
    日期:2014.1.17
    A series of bidentate monoanionic nitrogen ligands were designed and applied in the Pd-catalyzed oxidative Heck reaction of arenes with alkenes. Significant ligand-accelerated effects were observed, and direct C-H functionalized products were formed in high yields with meta-selectivity.
