    摘要:
    比较开链仲,仲-1,2-二醇的双-(R)-或双-(S)-MPA酯衍生物的室温和低温1 H NMR光谱,可轻松确定其相对立体化学,有时甚至是绝对构型。如果二醇是抗性的,则其绝对构型可以直接从ΔδT1T2的符号推导出对于取代基R 1 / R 2,但如果二醇的相对立体化学是顺式,则其绝对构型的分配需要制备两种衍生物(双-(R)-和双-(S)-MPA酯) ,其室温的比较1 1 H NMR谱,并计算该Δδ的RS次甲基Hα(R 1)和Hα(R 2)和R 1 / R 2质子的符号。这些相关性的可靠性通过用作模型化合物的已知绝对构型的17种二醇进行了验证。

  • Asymmetric Aldol Reaction Using Immobilized Proline on Mesoporous Support
    作者:Félix Calderón、Raquel Fernández、Félix Sánchez、Alfonso Fernández-Mayoralas
    DOI:10.1002/adsc.200505058
    日期:2005.8
    The aldol reaction of hydroxyacetone with different aldehydes using immobilized proline on a mesoporous support, assisted by heat and microwaves, has been explored. It was found that heterogenized L-proline on MCM-41 catalyzed aldol reactions in both hydrophilic and hydrophobic solvents, and provided stereoselectivities in some cases complementary to the homogeneous catalyst. The heterogeneous catalysts

The reactions tolerate a small amount of water (<4 vol %), do not require inert reaction conditions and preformed enolate equivalents, and can be conveniently performed at room temperature in various solvents. In addition, reaction conditions that facilitate catalyst recovery as well as immobilization are described. Finally, mechanistically related addition reactions such as

  • Poly(Ethylene Glycol)-Supported Proline: A Versatile Catalyst for the Enantioselective Aldol and Iminoaldol Reactions
    作者:Maurizio Benaglia、Mauro Cinquini、Franco Cozzi、Alessandra Puglisi、Giuseppe Celentano
    DOI:10.1002/1615-4169(200207)344:5<533::aid-adsc533>3.0.co;2-y
    日期:2002.7
    (2S,4R)-4-Hydroxyproline has been anchored to the monomethyl ether of poly(ethylene glycol), M-w 5000, by means of a succinate spacer to afford a soluble, polymer-supported catalyst (PEG-Pro) for enantioselective aldol and iminoaldol condensation reactions. This organic catalyst can be considered as a minimalistic version of a type I aldolase enzyme, with the polymer chain replacing the enzyme's peptide backbone, and the proline residue acting as the enzyme's active site. In the presence of PEG-Pro (0.25 - 0.35 mol equiv.), acetone reacted with enolizable and non-enolizable aldehydes and imines to afford beta-ketols and beta-aminoketones in good yield and high enantiomeric excess (ee), comparable to those obtained using non-supported proline derivatives as the catalysts. Extension of the PEG-Pro-promoted condensation to hydroxyacetone as the aldol donor opened an access to synthetically relevant anti-alpha,beta-dihydroxyketones and syn-alpha-hydroxy- beta-aminoketones, that were obtained in moderate to good yields, and good to high diastereo- and enantioselectivity. Exploiting its solubility properties, the PEG-Pro catalyst was easily recovered and recycled to promote all of the above-mentioned reactions, that occurred in slowly diminishing yields but virtually unchanged ee's.
    (2S,4R)-4-羟基脯氨酸通过succinateSpacer键合到分子量为5000的单甲醚聚乙二醇(PEG)上,制备成可溶性、载体化催化剂(PEG-Pro),用于具有立体选择性的aldol和iminoaldol缩合反应。该有机催化剂可被认为是I型aldol酶的极简版本,其中聚乙二醇链替代了酶的肽主链,脯氨酸残基则充当了酶的活性中心。在PEG-Pro(0.25-0.35mol当量)存在下,丙酮与可烯醇化和不可烯醇化的醛类以及亚胺反应,以良好收率和高对映体过量值得到了β-酮醇和β-氨基酮;其结果与采用非载体化脯氨酸衍生物作为催化剂时所获得的结果相当。将PEG-Pro催化的缩合反应推广到羟基丙酮作为aldol供体,即可获得具有合成价值的anti-α,β-二羟基酮和syn-α-羟基-β-氨基酮;这类产物具有中等到良好的收率,并表现出良好至极佳的双和对映选择性。利用其溶解性能,PEG-Pro催化剂易于回收并循环再利用,可用来推动上述所有反应;这些反应的收率虽逐步减小,但对映体过量值几乎不变。
  • Seebach’s oxazolidinone is a good catalyst for aldol reactions
    作者:Carles Isart、Jordi Burés、Jaume Vilarrasa
    DOI:10.1016/j.tetlet.2008.07.028
    日期:2008.9
    Seebach's proline-derived oxazolidinone 2d overcomes (S)-proline and is at least as efficient as (S)-5(pyrrolidin-2-yl)tetrazole in several organocatalytic aldol reactions examined. A quick exchange takes place between 2d and carbonyl Compounds that gives new bicyclic oxazolidinones, in equilibrium with the very minor active species (enamines). Maximum yields of the aldols (beta-hydroxy ketones) were achieved after 1-4 h when, with proline, they are attained after 30-48 h. (c) 2008 Elsevier Ltd. All rights reserved.
