    Double Diastereocontrol in Bifunctional Thiourea Organocatalysis: Iterative Michael–Michael–Henry Sequence Regulated by the Configuration of Chiral Catalysts
    摘要:
    The importance and reactivity consequences of the double diastereocontrol in noncovalent bifunctional organocatalysis were studied. The results suggest that the bifunctional thioureas can have synthetic limitations in multicomponent domino or autotandem catalysis. Nevertheless, we provided a means to exploit this behavior and used the configuration of the chiral catalyst as a control element in organo-sequential reactions.

  • 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。

    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。

    A highly efficient strategy for the kinetic resolution of Michael adducts was realized using a chiral N‐heterocyclic carbene catalyst. The kinetic resolution provides a new convenient route to single diastereomers of cyclohexenes and Michael adducts in good yields with high enantiomeric excesses (up to 99 % ee with a selectivity factor of up to 458). This “two flies with one swat” concept allows the

Its catalytic activity in Michael additions of 1,3‐dicarbonyl nucleophiles to trans‐β‐nitrostyrene derivatives provides excellent enantioselectivities (up to >99% ee).
