    Pinacolatoboron fluoride (pinBF) is an efficient fluoride transfer agent for diastereoselective synthesis of benzylic fluorides
    摘要:
    The incorporation of alkoxy ligands within a range of alkoxyfluoroboranes and dialkoxyfluoroboranes results in fluoroborane reagents with attenuated Lewis acidity and increased ability to donate fluoride ion(s) when compared to boron trifluoride itself. Pinacolatoboron fluoride (pinBF), prepared in situ from BF3 center dot OEt2 and bis(O-trimethylsilyl)pinacol, has been identified as an efficient fluoride donor which allows highly stereoselective S(N)1-type epoxide ring-opening (with retention of configuration) of a range of trans-beta-methyl-substituted aryl epoxides to give the corresponding syn-fluorohydrins. The substrate scope of this transformation is more broad than the analogous protocol using boron trifluoride alone. (C) 2014 Elsevier Ltd. All rights reserved.

  • Copper-Catalyzed Regioselective Monodefluoroborylation of Polyfluoroalkenes en Route to Diverse Fluoroalkenes

    salts has rendered the products easily isolable, which greatly improved the synthetic practicality of the monodefluoroborylation reaction. Stoichiometric experiments indicate that the fate of the regioselectivity depends on the mode of β-fluorine elimination, which depends on the substrate. Further transformation of the boryl group has allowed facile preparation of fluoroalkene derivatives as exemplified
    多氟烯烃的单脱氟硼化已经在区域条件下通过铜催化以区域选择性的方式实现了。该方法已显示出极其广泛的底物,包括(二氟乙烯基)芳烃,四氟乙烯(TFE),(三氟乙烯基)芳烃和三氟甲基化的单氟烯烃。硼源的选择对于有效转化(二氟乙烯基)芳烃很重要。(BPIN)2是适合于与缺电子的芳基和(BNEP)衬底2对于那些具有富电子芳基的化合物。将(氟烯基)硼酸酯衍生化为相应的三氟硼酸钾盐使得产物易于分离,这极大地提高了单脱氟硼化反应的合成实用性。化学计量学实验表明区域选择性的命运取决于β-氟消除的模式,其取决于底物。硼烷基的进一步转化允许容易地制备氟代烯烃衍生物,如合成阿托伐他汀的氟代烯烃模拟物所举例说明的那样,其有效抑制了HMG-CoA还原酶的酶活性。

Herein, the borane-catalyzed coupling of alkyl fluorides with arenes (carbon–carbon bond formation) and carboxylic acids (carbon–oxygen bond formation) has been developed using transborylation reactions to achieve catalytic
    鉴于氟碳键断裂的高热力学障碍,碳氟键的活化和功能化是一个重大的合成挑战。化学计量氢化硼硼烷介导的CF功能化最近出现,但尚未被催化。在本文中,已经开发出了硼烷催化的烷基氟与芳烃(形成碳-碳键)和羧酸(形成碳-氧键)的偶联反应,以实现催化转化。在各种结构上和电子分化芳烃和羧酸的使用9-硼杂双环[3.3.1]壬烷(H-达到成功的C-C和C-O耦合乙-9-BBN)作为催化剂和频哪醇硼烷(HBpin),具有宽泛的官能团耐受性。实验和计算研究表明碳-碳和碳-氧偶联反应的机理二分法。乙-F transborylation(B-F / B-H复分解)F-之间乙-9-BBN和HBpin启用碳-碳键形成的催化周转,而烷基氟化物和acyloxyboronic酯之间的直接交换(C-F / B -O复分解)被提议用于碳-氧偶联,其中H - B -9-BBN催化羧酸与HBpin的脱氢偶联。

    difluorides to generate axially chiral, tetrasubstituted monofluoroallenes in both good yields (27 examples >80%) and enantioselectivities (82–98% ee). Compared to previously reported synthetic routes to axially chiral allenes (ACAs) from prochiral substrates, a mechanistically distinct reaction has been developed: the enantiodiscrimination between enantiotopic fluorides to set an axial stereocenter.

    在这里,我们报告了炔丙基二氟化物的铜催化甲硅烷基化以产生良好的产率(27 个实例 >80%)和对映选择性(82-98% ee)的轴向手性、四取代的单氟丙二烯。与先前报道的从前手性底物合成轴向手性丙二烯 (ACA) 的路线相比,已经开发了一种机制上不同的反应:对映体氟化物之间的对映体区分以设置轴向立体中心。DFT 计算和振动圆二色性 (VCD) 表明,从烯基铜中间体中消除 β-氟化物可能通过顺-β-氟化物消除途径进行,而不是通过反-消除途径。研究了 C1 对称 Josiphos 衍生配体对反应性和对映选择性的影响。该报告不仅展示了烯基铜物种(如其烷基对应物)可以进行 β-氟化物消除,而且这种消除可以以对映选择性方式实现。

    The first example of catalytic enantioselective allylboration and crotylboration of simple ketones is described. High enantioselectivity (up to 93% ee) was obtained using 3 mol % CuF-iPr-DuPHOS as a chiral catalyst and 4.5 mol % La(OiPr)3 as a cocatalyst. Mechanistic studies strongly suggested that the active nucleophile of the present reaction is an allylcopper, and that La(OiPr)3 facilitates the
