  • Formate as a CO surrogate for cascade processes: Rh-catalyzed cooperative decarbonylation and asymmetric Pauson–Khand-type cyclization reactions
    作者:Hang Wai Lee、Albert S. C. Chan、Fuk Yee Kwong
    DOI:10.1039/b702718d
    日期:——
    A rhodium-(S)-xyl-BINAP complex-catalyzed tandem formate decarbonylation and [2 + 2 + 1] carbonylative cyclization is described; this cooperative process utilizes formate as a condensed CO source, and the newly developed cascade protocol can be extended to its enantioselective version, providing up to 94% ee of the cyclopentenone adducts.
    介绍了铑-(S)-xyl-BINAP配合物催化的甲酸脱羰和[2 + 2 + 1]羰基化环化联用反应;这种协同过程利用甲酸作为浓缩的CO源,新开发的级联方案可以扩展到其对映选择性版本,提供的环戊烯酮加成物的对映体过量值高达94%。

    operationally simple protocol allows both catalyst and reactants to be handled under air without precautions. Various enynes were transformed to the corresponding bicyclic cyclopentenones in good yield and enantiomeric excess (up to 95 % ee). A study of the electronic effects of the enyne substrates revealed a correlation between the electronic properties of the substrates and the ee value obtained in
    开发了一种有趣的铑催化的不对称含水Pauson-Khand型反应。发现手性阻转异构体二吡啶基二膦配体在该系统中是高度有效的。该操作简单的方案允许催化剂和反应物都在空气中进行处理而无需采取预防措施。将各种烯炔以良好的收率和对映体过量(至多95%ee)转化为相应的双环环戊烯酮。对烯炔底物的电子效应的研究表明,底物的电子性质与Pauson-Khand型反应产物中获得的ee值之间存在相关性。从Hammett研究中观察到线性自由能关系。
  • Rh(I)-Catalyzed Asymmetric Intramolecular Pauson-Khand Reaction in Aqueous Media
    作者:Young Keun Chung、Won Hyuck Suh、Mira Choi、Sang Ick Lee
    DOI:10.1055/s-2003-41044
    日期:——
    The first rhodium-BINAP complex-catalyzed enantioselective Pauson-Khand reaction in aqueous media, which is accelerated by surfactant, is reported. The chiral rhodium catalyst is easily prepared in situ from 1 equivalent of [Rh(cod)Cl]2 and 2 equivalents of BINAP under 1 atm of CO and a temperature of 60 °C or 90 °C. Ee’s up to 96% were achieved for the intramolecular Pauson-Khand reaction, but the yields are highly dependent upon the substrate itself.
    报告了一种在水相介质中催化的首个铑-BINAP配合物催化的对映选择性Pauson-Khand反应,该反应受到表面活性剂的加速。手性铑催化剂可以在1 atm CO和60°C或90°C的条件下,直接从1当量的[Rh(cod)Cl]2和2当量的BINAP原位制备。对于分子内Pauson-Khand反应,酰化率可达到96%,但产率高度依赖于底物本身。
  • Electronic and Steric Effects of Atropisomeric Ligands SYNPHOS® and DIFLUORPHOS®vs. BINAPs in Rh(I)-Catalyzed Asymmetric Pauson–Khand Reaction

    日期:2007.8.6
    electronic and steric effects of chiral biaryl diphosphine ligands on the Rh(I)-catalyzed asymmetric Pauson–Khand type reaction were examined. We demonstrated that enantioselectivity and reaction yield were influenced by the electronic density on phosphorus, the dihedral angle of ligands and the electronic density of the alkyne substrate. Ligands bearing a narrower dihedral angle than Binap, such as Synphos
    检查了手性联芳基二膦配体对Rh(I)催化的不对称Pauson-Khand型反应的电子和空间效应。我们证明对映选择性和反应产率受磷的电子密度,配体的二面角和炔烃底物的电子密度的影响。与Binap型配体相比,发现具有比Binap窄的二面角的配体,例如Synphos(L4)和Difluorphos(L5),大大提高了反应的对映选择性。具有去屏蔽的膦的配体,例如p -CF 3 -Binap(L3)和Difluorphos(L5)提供了比Binap更好的对映选择性,并减少了副产物的形成,特别是对于电子贫乏的炔烃底物。

    Iridium–chiral diphosphine complex catalyzes an enantioselective intramolecular Pauson–Khand-type reaction to give various chiral bicyclic cyclopentenones. The enantioselective reaction proceeds more smoothly and enantioselectively under a lower partial pressure of carbon monoxide. Moreover, aldehyde can be used as a CO source in the enantioselective carbonylative coupling.
    铱-手性二膦配合物催化对映选择性分子内Pauson-Khand型反应,生成各种手性双环环戊烯酮。在较低的一氧化碳分压下,对映选择性反应更平稳和对映选择性地进行。此外,在对映选择性羰基化偶联中,可以将醛用作CO源。
