  • Synthesis of Chiral β-Borylated Carboxylic Esters via Nickel-Catalyzed Asymmetric Hydrogenation
    作者:Zhengyu Han、Gang Liu、Xianghe Zhang、Anqi Li、Xiu-Qin Dong、Xumu Zhang
    DOI:10.1021/acs.orglett.9b00994
    日期:2019.6.7
    The highly efficient Ni-catalyzed asymmetric hydrogenation of β-boronic ester substituted-α,β-unsaturated carboxylic esters was successfully developed using (S,S)-Ph-BPE as the ligand. A series of chiral β-borylated carboxylic esters were obtained with high yields (94%–99% yields) and excellent enantioselectivities (89%–99% ee). The gram-scale asymmetric hydrogenation with a low catalyst loading (0
    以(S,S)-Ph-BPE为配体成功地开发了高效Ni催化的β-硼酸酯取代的α,β-不饱和羧酸酯的不对称加氢反应。获得了一系列高收率(94%–99%收率)和出色的对映选择性(89%–99%ee)的手性β-硼化羧酸酯。具有低催化剂负载量(0.25 mol%)的克级不对称氢化和氢化产物的合成转化证明了该方法的巨大合成效用。
  • Copper(II)-Catalyzed β-Borylation of Acetylenic Esters in Water

    presence of bis(pinacolato)diboron and catalytic amounts of both copper(II) and 4-picoline, substituted alkynoates undergo borylation in a regio-, stereo-, and chemoselective fashion. The reaction is performed under mild conditions using water as solvent and open to the atmosphere to exclusively afford (Z)-β-boryl-α,β-unsaturated esters. A method for the β-borylation of alkynoates has been developed

  • Copper-catalyzed boration of activated alkynes. Chiral boranes via a one-pot copper-catalyzed boration and reduction protocol
    作者:Ho-Young Jung、Xinhui Feng、Hyohyun Kim、Jaesook Yun

    Phosphine–copper(I) complexes efficiently catalyzed the mono-boration of electron-deficient alkynes in the presence of MeOH and also catalyzed conjugate reductions of alkenylboronates bearing an electron-withdrawing group. The mono-addition of bis(pinacolato)diboron to alkynes catalyzed by a copper–Xantphos complex produced vinylboronates with high regio and stereoselectivity and asymmetric reduction
    在甲醇存在下,磷化氢-铜(I)络合物可有效催化缺电子炔烃的单硼酸酯化反应,还可以催化带有吸电子基团的烯基硼酸酯的共轭还原反应。在铜-Xantphos络合物的催化下,将双(频哪醇)二硼单价加成到炔烃上,产生了具有高区域和立体选择性的乙烯基硼酸酯,并且通过手性铜-双膦催化剂使乙烯基硼酸酯不对称还原,从而可以合成具有高对映选择性的有价值的手性硼烷。一锅硼酸化/不对称还原α,β-不饱和炔酸酯可以用单一的铜-膦催化剂进行。

  • Phosphine-Catalyzed <i>Anti</i>-Hydroboration of Internal Alkynes
    作者:Kazunori Nagao、Ayaka Yamazaki、Hirohisa Ohmiya、Masaya Sawamura
    DOI:10.1021/acs.orglett.8b00390
    日期:2018.4.6
    Trialkylphosphine organocatalysts have enabled regioselective anti-hydroboration of internal, alkynes with pinacolborane reagents to provide (E)-disubstituted alkenylboronate compounds. The alkenyl-boronate can be used for derivatizations, such as protodeborylation, Suzuld-Miyaura coupling, conjugate reduction, and Diels-Alder reactions.
