  • Chiral-at-Metal Rh(III) Complex-Catalyzed Decarboxylative Michael Addition of β-Keto Acids with α,β-Unsaturated 2-Acyl Imidazoles or Pyridine
    作者:Shi-Wu Li、Jun Gong、Qiang Kang
    DOI:10.1021/acs.orglett.7b00220
    日期:2017.3.17
    chiral-at-metal Rh(III) complex-catalyzed, highly efficient enantioselective decarboxylative Michael addition of β-keto acids with α,β-unsaturated 2-acyl imidazoles or pyridine has been developed, affording the corresponding adducts in 94–98% yield with up to 96% enantioselectivity. This protocol exhibits remarkable reactivity, as the complex with a Rh(III) loading as low as 0.05 mol % can catalyze the decarboxylative
    一种新制备的手性属Rh(III)络合物催化的β-酮酸与α,β-不饱和2-酰基咪唑吡啶的高效对映选择性脱羧迈克尔加成反应,在94- 98%的产率和高达96%的对映选择性。该方案显示出显着的反应活性,因为具有低至0.05 mol%的Rh(III)负载的络合物可以以克为单位催化脱羧Michael加成,而不会损失对映选择性。
  • Cooperative Lewis Acid Catalysis for the Enantioselective C(sp<sup>3</sup>)–H Bond Functionalizations of 2-Alkyl Azaarenes
    作者:Pramod Rai、Satyadeep Waiba、Kakoli Maji、Dibyaranjan Sahoo、Biplab Maji
    DOI:10.1021/acs.orglett.1c03387
    日期:2021.11.19
    Herein, we describe the enantioselective C(sp3)–H bond functionalizations of 2-alkyl azaarenes using a cooperative dual Lewis acid catalysis. An achiral Lewis acid activates the unactivated azaarene partner without the need for a strong base. Orthogonally, a chiral-at-metal Lewis acid catalyst enables LUMO lowering and induces chirality. This method tolerates a range of complex molecular scaffolds
    在此,我们描述了使用协同双路易斯酸催化对 2-烷基氮杂芳烃进行对映选择性 C(sp 3 )-H 键官能化。非手性路易斯酸可激活未活化的氮杂芳烃伴侣,而无需强碱。正交地,手性路易斯酸催化剂能够降低 LUMO 并诱导手性。该方法可耐受一系列复杂的分子支架,并表现出良好的收率和选择性,同时接受各种官能团。
  • Enantioselective Michael addition reactions in water using a DNA-based catalyst
    作者:Yinghao Li、Changhao Wang、Guoqing Jia、Shengmei Lu、Can Li
    DOI:10.1016/j.tet.2013.05.133
    日期:2013.8
    Enantioselective Michael addition reactions of malononitrile and cyanoesters to α,β-unsaturated 2-acylimidazoles can be achieved in water using a DNA-based catalyst consisting of double-stranded DNA and copper(II) complex. Quantitative conversions and good enantioselectivities (up to 84% ee) are obtained for a wide range of substrates. The UV–vis absorption and circular dichroism (CD) indicate that
    丙二腈基酯对α,β-不饱和2-酰基咪唑的对映选择性迈克尔加成反应可以在中使用由双链DNA和(II)配合物组成的基于DNA的催化剂完成。对于多种底物,均可获得定量转化率和良好的对映选择性(最高84%ee)。紫外可见吸收和圆二色性(CD)表明,(II)配合物可能通过小沟结合与鲑鱼睾丸DNA相互作用。
  • An enantioselective sulfa-Michael addition of alkyl thiols to α,β-unsaturated 2-acyl imidazoles catalyzed by a bifunctional squaramide
    作者:Rupesh K. Jha、Subhrajit Rout、Harshit Joshi、Arko Das、Vinod K. Singh
    DOI:10.1016/j.tet.2019.130800
    日期:2020.1
    An enantioselective catalytic sulfa-Michael addition of alkyl thiols to α,β-unsaturated 2-acyl imidazoles using bifunctional organocatalysts is reported. The methodology works efficiently with low catalyst loading (1 mol%) to furnish sulfa-Michael adducts in excellent yields (up to 98%) and high enantioselectivities (up to 92% ee). A transition state model has been proposed to explain the stereochemical
    报道了使用双官能有机催化剂将烷基醇的对映选择性催化磺胺-迈克尔加成到α,β-不饱和2-酰基咪唑上。该方法以低催化剂负载量(1 mol%)有效地工作,以极好的收率(高达98%)和高对映选择性(高达92%ee)提供磺胺-迈克尔加成物。已经提出了过渡状态模型来解释反应的立体化学结果。
  • Catalytic Asymmetric Addition Reactions of Formaldehyde <i>N</i>,<i>N</i>-Dialkylhydrazone to Synthesize Chiral Nitrile Derivatives
    作者:Hang Zhang、Yao Luo、Chenhao Zhu、Shunxi Dong、Xiaohua Liu、Xiaoming Feng
    DOI:10.1021/acs.orglett.0c01857
    日期:2020.7.2
    A number of nitrile-containing chiral molecules were synthesized via asymmetric nucleophilic addition of formaldehyde N,N-dialkylhydrazone as the nitrile equivalent. Chiral N,N′-dioxide/metal salt complexes enabled the asymmetric addition reactions to both isatin-derived imines and α,β-unsaturated ketones, generating amino nitriles and 4-oxobutanenitrile derivatives in good yields with high enantioselectivities
    通过不对称的亲核加成甲醛N,N-二烷基alkyl作为腈当量,合成了许多含腈的手性分子。手性N,N′-二氧化物/属盐配合物能够使不对称的加成反应从伊斯丁衍生的亚胺和α,β-不饱和酮,以高收率和高对映选择性生成基腈和4-氧代丁腈生物。通过避免使用有毒腈试剂,广泛的底物范围以及将手性ad加合物向其他有价值的分子进行多用途转化,突出了该方案。
