  • Asymmetric Conjugate Addition of Nitromethane to Enones Catalyzed by Chiral N,N′-Dioxide-Scandium(III) Complexes

    Chalk it up as a “Sc”andal: The asymmetric conjugate addition of chalcone and “cinnamone” derivatives to nitromethane has been realized by using a simple and efficient scandium(III)–N,N′‐dioxide complex as the catalyst (see scheme). In the presence of 2–5 mol % catalyst loading, the corresponding products were formed in excellent yields (up to 99 %) and enantioselectivities (up to>99 % ee).
    以“ Sc”形式存在:将查尔酮和“肉桂酮”衍生物不对称共轭加成到硝基甲烷中,是通过使用简单有效的scan(III)-N,N'-二氧化物络合物作为催化剂实现的(参见方案) )。在2-5 mol%的催化剂负载下,形成的相应产物的收率(高达99%)和对映选择性(高达ee > 99%  )都非常好。
  • Scope and Mechanism of Enantioselective Michael Additions of 1,3-Dicarbonyl Compounds to Nitroalkenes Catalyzed by Nickel(II)−Diamine Complexes
    作者:David A. Evans、Shizue Mito、Daniel Seidel
    DOI:10.1021/ja0735913
    日期:2007.9.1
    Readily prepared Ni(II)-bis[(R,R)-N,N'-dibenzylcyclohexane-1,2-diamine]Br(2) was shown to catalyze the Michael addition of 1,3-dicarbonyl compounds to nitroalkenes at room temperature in good yields with high enantioselectivities. The two diamine ligands in this system each play a distinct role: one serves as a chiral ligand to provide stereoinduction in the addition step while the other functions
    容易制备的 Ni(II)-双[(R,R)-N,N'-二苄基环己烷-1,2-二胺]Br(2) 在室温下可催化 1,3-二羰基化合物与硝基烯烃的迈克尔加成反应温度高,产率高,对映选择性高。该系统中的两个二胺配体各自发挥不同的作用:一个作为手性配体在加成步骤中提供立体诱导,而另一个作为底物烯醇化的基础。还研究了催化剂内的配体改性,以促进脂肪族硝基烯烃、1,3-二酮和 β-酮酸的反应。Ni(II)-双[(R,R)-N,N'-di-p-bromo-benzylcyclohex-1,2-diamine]Br(2) 在这些情况下被发现是一种有效的催化剂。此外,单二胺络合物,Ni(II)-[(R,R)-N,N'-二苄基环己烷-1,2-二胺]Br(2),在水存在下催化加成反应。所提出的立体化学诱导模型显示与 X 射线结构分析一致。

    novel chiral thiourea containing a segment of privileged (2S)‐2‐pyrrolidinylmetan‐amine as well as a hydrophobic phosphoramide framework is described. The new organocatalyst exhibited good performance in asymmetric Michael additions, in a variety of systems including the formal [3+3] cyclization of cyclohexanone with arylidenepyruvates through a cascade process, which involves the asymmetric Michael

  • Highly Enantioselective Michael Addition of Nitroalkanes to Chalcones Using Chiral Squaramides as Hydrogen Bonding Organocatalysts

    日期:2010.12.3
    squaramide-based organocatalysts were facilely synthesized and applied as hydrogen bonding organocatalysts in the enantioselective Michael addition of nitroalkanes to chalcones. These organocatalysts promoted the Michael addition with low catalyst loading under high temperature (80 °C), affording the desired R or S enantiomers of the products flexibly in high yields with excellent enantioselectivities (93−96%
