    Zirconium-catalyzed and zirconium-promoted cyclization reactions of non-conjugated dienes with alkylmagnesium halides to give cycloalkylmethylmagnesium derivatives
    摘要:
    The stoichiometric reaction of certain non-conjugated dienes with n-Bu2ZrCp3 provides the corresponding zirconabicycles, such as trans-3-bis( cyclopentadienyl) zirconabicyclo [3.3.0] octane, that can be fully characterized by spectroscopic means. Their treatment with EtMgBr or n-BuMgCl in THF gives The corresponding monocyclic monomagnesium derivatives along with the corresponding alkene-ZrCp2 derivatives in high yields. In cases where the Grignard reagent is either sterically hindered or lacking P-HI little or no reaction may occur, although some, e.g., s-BuMgCl, react, albeit slowly, to give the expected products in high yields. In cases where either a Grignard reagent in diethyl ether or a dialkylmagnesium (irrespective of solvent) is used, the major product is the corresponding dimagnesio derivative. A couple of intramolecular transmetallation paths are proposed for these cases. The Cp2ZrCl2-catalyzed reaction of 1,6-heptadiene with EtMgBr fails to induce the desired bicyclization-ring opening sequence to give the corresponding monocyclic monomagnesium derivatives. On the other hand, the corresponding reaction with n-BuMgBr does proceed as desired to give the monocyclic monomagnesium product which contains a minor amount of the corresponding exo-methylene derivative. Only traces, if any, of the corresponding dimagnesium derivatives reported to be the major products in Et2O are formed. This procedure has been applied to catalytically convert several other dienes, i.e., (E)-1-phenyl-1,6-heptadiene, 2,4,4-trimethyl-1,6-heptadiene, diallyl (benzyl) amine, 1,7-octadiene and 1,2-diallylbenzene, into the corresponding monocyclized compounds in moderate to excellent combined yields.

    Mechanistic studies on Cu-catalyzed asymmetric additions of alkylzirconocene nucleophiles to racemic allylic halide electrophiles were conducted using a combination of isotopic labeling, NMR spectroscopy, kinetic modeling, structure-activity relationships, and new reaction development. Kinetic and dynamic NMR spectroscopic studies provided insight into the oligomeric Cu-ligand complexes, which evolve
    结合同位素标记、核磁共振光谱、动力学建模、构效关系和新反应发展,对催化的烷基茂亲核试剂向外消旋烯丙基卤化物亲电试剂的不对称加成进行了机理研究。动力学和动态 NMR 光谱研究提供了对低聚 Cu-配体配合物的洞察,这些配合物在反应过程中变得更快和更高的对映选择性。Cu 抗衡离子在选择不同途径和通过形成烯丙基中间体使起始材料外消旋方面发挥作用。我们量化了 Cu 催化的烯丙基异构化的速率,并确定了一系列发生烯丙基的形成和外消旋化的条件。我们开发了反应条件,其中外消旋烯丙基磷酸酯是使用新亚酰胺配体 D 的合适底物。D 还首次允许对外消旋七元环烯丙基进行高度对映选择性加成。使用烯丙基磷酸酯的反应的 1H 和 2H NMR 光谱实验表明烯丙基中间体的重要性,这些中间体通过 TMSCl 的作用形成或来自外来的源。总的来说,这些研究支持一种机制,即复杂的低聚催化剂既可以使起始材料外消旋,又

    remains a key challenge. Here we report a copper-catalysed dynamic kinetic asymmetric transformation using racemic substrates and alkyl nucleophiles. These nucleophiles have a pKa of ≥50, more than 25 orders of magnitude more basic than the nucleophiles that are typically used in such transformations. Organometallic reagents are generated in situ from alkenes by hydrometallation and give highly enantioenriched
    形成不对称碳-碳键的新反应的发展使化学家能够合成范围广泛的重要含碳分子,包括药剂、香料和聚合物。大多数获得对映异构体富集分子的策略依赖于从前手性底物生成新的立体中心或解析对映异构体的外消旋混合物。另一种策略——动态动力学不对称转化——涉及将外消旋原料转化为单一对映异构体产品,最大产率超过 50%。在催化的不对称烯丙基烷基化反应中使用稳定的亲核试剂(pKa < 25,其中 Ka 是酸解离常数)已被证明在这些过程中非常通用。反过来,在此类反应中使用不稳定的亲核试剂是困难的,并且仍然是一个关键挑战。在这里,我们报告了使用外消旋底物和烷基亲核试剂的铜催化动态动力学不对称转化。这些亲核试剂的 pKa ≥ 50,比此类转化中通常使用的亲核试剂碱性高 25 个数量级以上。有机金属试剂是通过氢属化从烯烃原位生成的,并在温和的反应条件下得到高度对映体富集的产物。该方法用于合成具有抗结核和麻风活性的天然产
