    9-氨基(9-脱氧)-表-奎宁催化的α,β-不饱和烯酮上硝基链烷烃的一般高对映选择性迈克尔加成反应:显着的加成作用
    摘要:
    报道了一种特别通用的方案,用于将硝基烷烃有机催化不对称迈克尔加成到α,β-不饱和烯酮上。迈克尔反应进展顺利,并以中等至优异的收率(55-99%)和良好至优异的对映选择性(65-99%ee)提供了所需的加合物。容易获得的非手性碱的加入显着增强了反应性,而没有损害对映选择性。

  • Primary Amine-Thioureas with Improved Catalytic Properties for “Difficult” Michael Reactions: Efficient Organocatalytic Syntheses of (S)-Baclofen, (R)-Baclofen and (S)-Phenibut
    作者:Michail Tsakos、Christoforos G. Kokotos、George Kokotos
    DOI:10.1002/adsc.201100636
    日期:2012.3
    Among the class of primary amine‐thioureas based on tert‐butyl esters of α‐amino acids, the most efficient organocatalyst for “difficultMichael reactions was identified. The derivative based on (S)‐di‐tert‐butyl aspartate and (1R,2R)‐diphenylethylenediamine provided the products of the reaction between aryl methyl ketones and nitroolefins in excellent yields and enantioselectivities. In addition
    在基于α-氨基酸叔丁基酯的伯胺硫脲类中,发现了“难”迈克尔反应最有效的有机催化剂。基于(S)-二叔丁基天冬氨酸盐和(1 R,2 R)-二苯基乙二胺的衍生物提供了芳基甲基酮与硝基烯烃之间反应的产物,收率和对映选择性极好。另外,这种新催化剂可以以低催化剂负载量(5mol%)使用。有效合成(S)-baclofen,(R)-baclofen和(S)-phenibut的方法突显了这种方法的实用性。
  • 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。

    作者:Wen Yang、Da-Ming Du
    DOI:10.1021/ol102294g
    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%

    DOI:10.2174/157017810791514652
    日期:2010.7.1
    Simple chiral primary amine-thiourea catalysts derived from chiral 1,2-diphenylethylenediamine were found to catalyze direct Michael addition of aromatic ketones to nitroolefins with good enantioselectives (up to 86% ee) and excellent yields (up to 97%) for a broad range of substrates and successfully used in the preparation of (R)-Balcofen.

  • Enantioselective addition of aryl ketones and acetone to nitroalkenes organocatalyzed by carbamate-monoprotected cyclohexa-1,2-diamines
    作者:Jesús Flores-Ferrándiz、Alexander Stiven、Lia Sotorríos、Enrique Gómez-Bengoa、Rafael Chinchilla
    DOI:10.1016/j.tetasy.2015.07.011
    日期:2015.9
    Enantiomerically pure carbamate-monoprotected trans-cyclohexane-1,2-diamines are used as chiral organocatalysts for the addition of aryl ketones and acetone to nitroalkenes to give enantioenriched beta-substituted gamma-nitroketones. The reaction was performed in the presence of 3,4-dimethoxybenzoic acid as an additive, in chloroform as the solvent at room temperature, achieving enantioselectivities up to 96%. Theoretical calculations are used to justify the observed sense of the stereoinduction. (C) 2015 Elsevier Ltd. All rights reserved.
