    摘要:
    脯氨酸的吡咯烷基主链的修饰在提高催化效率和对映选择性方面还不是很成功。在这项研究中,发现脯氨酸的 C4 位上的顺式取代与含氮基团对芳香醛与环己酮直接羟醛反应的催化剂的反应性和选择性都有显着影响。与母体 L-脯氨酸相比,cis-4-Pyrrolidin-1-yl-L-proline 表现出显着改善的反应性、非对映选择性和对映选择性,提供高分离产率(高达 99%)和出色的非对映选择性(> 99:1 dr)和对映选择性 (> 99% ee)。发现三氟乙酸的存在对于该催化剂的出色性能至关重要。

    日期:2014.5
    With heterocyclic ketones or cyclohexanone, the aldol reactions gave products in high yields and with respectable enantioselectivities (87–99% ee) and diastereoselectivities (up to >99:1 anti/syn). The catalyst could be recycled and reused up to seven times resulting in good yields and with good selectivities. This catalyst is also efficient in large-scale reactions with the enantioselectivities remaining

    amine organocatalysts, derived from natural primary amino acids, in combination with 2,4-dinitrophenol (DNP) have proven to be efficient in the presence of brine without further addition of organic solvents. The system formed by 1f and DNP was the most efficient one; it can catalyze the direct aldol reaction with a broad range of ketones and aromatic aldehydes, giving the corresponding aldol products
    由六种衍生自天然伯氨基酸的伯胺有机催化剂与2,4-二硝基苯酚(DNP)组合而成的有机催化系统已证明在盐水存在下无需进一步添加有机溶剂即可有效。由1f和DNP组成的系统是最有效的系统。它可以与广泛的酮和芳族醛催化直接的羟醛反应,以高收率提供相应的羟醛产物,具有高达近乎完美的非对映体和对映体选择性(最高99/1顺/反,对映体> 99%ee)。

    作者:Shi Li、Xiangkai Fu、Chuanlong Wu
    DOI:10.1007/s11164-011-0336-5
    日期:2012.1
    Highly enantioselective, recoverable and cheap cysteine derivatives have been developed with improved solubility properties in common, nonpolar organic solvents. The reactions were catalyzed using 5 mol% 1e, and the aldol products could be obtained with up to 99:1 syn/anti ratio and >99% ee. The catalyst could be easily recovered and reused, with only a slight decrease of enantioselectivity observed for five cycles. Catalyst 1e can be efficiently used in large-scale reactions with enantioselectivity being maintained at the same level, which offers great possibility for application in industry. (i) Direct aldol reactions proceeded in 1,2-dichloroethane using simple procedures. (ii) Direct S-acylation of cysteine to give organocatalysts 1a–f can be economically carried out easily in a single step from commercially available sources, with both enantiomers being readily available. (iii) 5 mol% catalyst 1e was sufficient to furnish the aldol products in excellent yields (up to 93%) and enantioselectivities (up to 99%). (iv) Catalyst 1e could be easily recovered and reused, and also can be efficiently used in large-scale reactions with enantioselectivity being maintained at the same level, which offers great possibility for applications in industry.

    Organic-catalyzed stereoselective reactions have gained attention because they avoid the problems associated with metal catalysts, but existing catalysts based on proline have limitations. Therefore, (R,R)-(+)-1,2-diphenylethylenediamine (DPEN) was selectively mono-N-alkylated through reductive alkylation and used as an organic catalyst for the aldol reaction. Using a variety of aldehydes in the catalytic
    由于有机催化的立体选择反应避免了与金属催化剂有关的问题,因此引起了人们的关注,但是现有的基于脯氨酸的催化剂存在局限性。因此,(R,R)-(+)-1,2-二苯基乙二胺(DPEN)通过还原烷基化被选择性地单-N-烷基化,并用作醛醇缩合反应的有机催化剂。在催化的醛醇缩合反应中使用多种醛,N-烷基化的DPEN催化剂从伯胺发展为烯胺和亚胺中间体,并获得了高收率(80%)和对映选择性(90%)。发现氮的位阻手性二胺的-烷基取代基和铵部分与芳族醛的氧之间的氢键决定了对映选择性。测试了各种芳族​​醛,并且吸电子取代基导致了良好的产率,而供电子取代基通过使醛的羰基失活而导致了较差的产率。此外,邻位取代基比对位取代基具有更高的立体选择性,因为立体效果得到增强。
