  • Metal-Free Catalytic Boration at the β-Position of α,β-Unsaturated Compounds: A Challenging Asymmetric Induction
    作者:Amadeu Bonet、Henrik Gulyás、Elena Fernández
    DOI:10.1002/anie.201001198
    日期:——
    Enantiomerically enriched secondary organoboronates containing β‐carbonyl functional groups have been prepared using an unprecedented organocatalytic system (see scheme). The use of chiral tertiary phosphorus compounds induced ee values of up to 95 % in the absence of transition metals.
    使用史无前例的有机催化体系制备了含有β-羰基官能团的对映体富集的仲有机硼酸酯(参见方案)。在不存在过渡金属的情况下,使用手性叔磷化合物可导致ee值高达95%。
  • A Chiral 6-Membered <i>N</i>-Heterocyclic Carbene Copper(I) Complex That Induces High Stereoselectivity
    作者:Jin Kyoon Park、Hershel H. Lackey、Matthew D. Rexford、Kirill Kovnir、Michael Shatruk、D. Tyler McQuade
    DOI:10.1021/ol1021756
    日期:2010.11.5
    A chiral 6-membered annulated N-heterocyclic (6-NHC) copper complex that catalyzes β-borylations with high yield and enantioselectivity was developed. The chiral 6-NHC copper complex is easy to prepare on the gram scale and is very active, showing 10 000 turnovers at 0.01 mol % of catalyst without significant decrease of enantioselectivity and with useful reaction rates.
    开发了一种手性的六元环状N-杂环(6-NHC)铜络合物,它以高收率和对映选择性催化β-硼化。手性6-NHC铜络合物易于按克规模制备,并且非常活泼,在0.01 mol%的催化剂下显示出1万的周转率,而对映选择性没有显着降低,并且具有有用的反应速率。
  • Organocatalytic versus Iron-Assisted β-Boration of Electron-Deficient Olefins
    作者:Amadeu Bonet、Cristina Sole、Henrik Gulyás、Elena Fernández
    DOI:10.1002/asia.201000826
    日期:2011.4.4
    Combo effects: The first example of an iron‐mediated β‐boration of activated olefins is reported. The origin and the benefits of the catalytic activity associated with the presence of iron have been questioned and carefully studied. The iron system has been compared to the organocatalytic β‐boration of α,β‐unsaturated esters, ketones, and imines (see scheme; acac=acetylacetonate, pin=pinacol).
    组合效应:报道了铁介导的活化烯烃的β-硼酸酯化的第一个例子。与铁的存在有关的催化活性的起源和益处已受到质疑和仔细研究。已将铁系统与α,β-不饱和酯,酮和亚胺的有机催化β-硼酸酯(参见方案; acac =乙酰丙酮酸酯,pin =频哪醇)进行了比较。
  • Axially chiral P-N ligands for the copper catalyzed β-borylation of α,β-unsaturated esters
    作者:William J. Fleming、Helge Müller-Bunz、Vanesa Lillo、Elena Fernández、Patrick J. Guiry
    DOI:10.1039/b900741e
    日期:——
    The synthesis and resolution of a new axially chiral Quinazolinap ligand are reported. The application of this and other related P-N ligands to the copper catalyzed β-borylation of α,β-unsaturated esters resulted in conversions of up to 100% and ee values of up to 79%. A diastereomerically pure palladacycle of the new ligand was characterised by X-ray crystallography.
    报道了一种新型轴手性喹唑啉啶配体的合成与解析。将该配体及其他相关P-N配体应用于铜催化的α,β-不饱和酯的β-硼化反应中,获得了高达100%的转化率和高达79%的ee值。通过X射线晶体学方法对新配体的一种纯对映异构钯环进行了表征。
  • Asymmetric β-Boration of α,β-Unsaturated Esters with Chiral (NHC)Cu Catalysts

    DOI:10.1021/om800946k
    日期:2009.1.26
    Copper complexes containing chiral N-heterocyclic carbene ligands catalyze the regioselective nucleophilic boryl attack at the β-carbon of α,β-unsaturated esters with enantioselectivities up to 74% ee, depending on the nature of the ester group.
    含有手性N-杂环卡宾配体的铜络合物催化α,β-不饱和酯的β-碳的区域选择性亲核硼基进攻,对映选择性高达74%ee,具体取决于酯基的性质。
