    Synthesis and application of novel imidazole and 1H-tetrazolic acid containing catalysts in enantioselective organocatalyzed Diels–Alder reactions
    摘要:
    Herein we report studies on the organocatalytic Diels-Alder reaction using a variety of catalysts capable of activating alpha,beta-unsaturated carbonyl compounds for reactions with dienes. The structurally attractive catalysts 4 and 14 were utilized in the enantioselective organocatalytic Diels-Alder reactions. Catalyst 4 provided the products in fair yields and more importantly in good enantioselectivities of up to 83% ee. Catalyst 14 was synthesized in high yield and was assessed in the enantioselective organocatalytic Diels-Alder reaction. Catalyst 14 proved to be a highly active and selective catalyst providing the products in high yield and high enantioselectivities up to 95% ee. (C) 2009 Elsevier Ltd. All rights reserved.

    properly modified enantiomerically pure imidazolidinone inside a stainless steel column in the presence of dodecanol and toluene as porogens afforded the first example of a chiral organocatalyst immobilized onto a monolithic reactor. Organocatalyzed cycloadditions between cyclopentadiene and cinnamic aldehyde were performed under continuous-flow conditions; by optimizing the experimental set up, excellent
    在十二烷基醇和甲苯作为致孔剂的存在下,在不锈钢塔内将二乙烯基苯与适当改性的对映体纯的咪唑啉酮进行自由基共聚反应提供了固定在整体式反应器上的手性有机催化剂的第一个实例。环戊二烯与肉桂醛之间的有机催化环加成反应是在连续流动条件下进行的。通过优化实验设置,可以获得出色的对映选择性(在25°C时为90%ee)和高生产率(高于330),因此表明催化反应器可以有效地连续生产对映体富集的化合物。同样的催化反应器也被用来连续地进行三种不同的立体选择性转化。,依次在手性色谱柱内(Diels–Alder,1,3-偶极硝酮-烯烃环加成和Friedel–Crafts烷基化);在前两个反应的情况下获得了极好的结果(分别在25°C下达到99%的收率,93%ee和71%的收率,90%ee)。除了简化产物回收之外,整体式反应器在搅拌烧瓶中的性能优于相同的负载型有机催化剂,并且可以连续工作8天以上。

They were used in organocatalyzed Diels–Alder cycloadditions between cyclopentadiene and different aldehydes, affording results comparable to those obtained with the nonsupported catalyst (up to 91% yield and 92% ee in the model reaction between cyclopentadiene and cinnamic aldehyde). The catalysts were recovered from the reaction mixture

    [reaction: see text] A novel binaphthyl-based diamine (R)-2 was designed and synthesized. A protonic acid-(R)-2 salt catalyst has the advantage of exhibiting unprecedented high exo selectivity in the asymmetric Diels-Alder reaction of alpha,beta-unsaturated aldehydes.

    Abstract New chiral imidazolidinone with an indole group was synthesized and used to catalyze the Diels–Alder reaction of α,β-unsaturated aldehyde with diene. High enantiomeric excesses and good yields were obtained. The reaction media were also surveyed.

    Bronsted acid-assisted chiral Lewis acid (BLA) was highly effective as a chiral catalyst for the enantioselective Diels−Alder reaction of both α-substituted and α-unsubstituted α,β-enals with various dienes. Hydroxy groups in optically active binaphthol derivatives and boron reagents with electron-withdrawing substituents were used as Bronsted acids and Lewis acids, respectively. Intramolecular Bronsted
    布朗斯台德酸辅助的手性路易斯酸 (BLA) 作为手性催化剂非常有效,可用于 α-取代和 α-未取代的 α,β-烯醛与各种二烯的对映选择性 Diels-Alder 反应。光学活性联萘酚衍生物中的羟基和具有吸电子取代基的硼试剂分别用作布朗斯台德酸和路易斯酸。手性 BLA 催化剂中的分子内布朗斯台德酸在加速 Diels-Alder 反应速率和产生高水平的对映选择性方面发挥了重要作用。特别是,由于手性 BLA 催化剂中羟基芳基在过渡态组装中的分子内氢键相互作用和有吸引力的 π-π 供体-受体相互作用,实现了优异的对映选择性。
