  Poly(Ethylene Glycol)-Supported Proline: A Versatile Catalyst for the Enantioselective Aldol and Iminoaldol Reactions

  摘要：

  (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。

  Study of asymmetric aldol and Mannich reactions catalyzed by proline–thiourea host–guest complexes in nonpolar solvents

  摘要：

  A proline-thiourea host-guest complex has been described as a good catalyst for asymmetric reactions such as aldol and Mannich reactions. High stereoselectivities were obtained under optimal conditions. Thiourea was observed to have an important effect on the reactivity and selectivity, even in an unconventional nonpolar reaction medium and without the need to utilize low temperatures. This proline-thiourea host-guest system has the ability to participate in a hydrogen bonding network. (C) 2013 Elsevier Ltd. All rights reserved.

  Enantioselective Organocatalytic Mannich Reactions with Autocatalysts and Their Mimics

  摘要：

  The Mannich reactions previously extensively investigated with organocatalysis of L-proline and other related small molecules were reinvestigated with detailed stercochemical analysis of their autocatalysis pathways, through employment of both the products themselves and their close structural mimics as the catalysts. These organo-autocatalytic processes function as meaningful molecular models toward understanding the origin and maintenance of homochirality under biologically relevant conditions.

  Isosteviol‐amino acid conjugates were synthesized and used as chiral catalysts for the asymmetric three‐component Mannich reaction with hydroxyacetone as donor molecule. Good yields (up to 98%) and excellent stereoselectivities (up to 97:3 dr and 99% ee) were achieved in a short reaction time. In addition, syn‐ or anti‐configurations of α‐hydroxy‐β‐amino carbonyl compounds were obtained as main products

  A novel one-pot three-component asymmetric Mannich reaction using [EMIm][Pro] (1) as a catalyst has been developed. By employing this new reaction system, a variety of optically active β-amino carbonyl compounds were synthesized in up to 99 % yield with up to >99 dr and >99 % ee.

  Efficient chiral catalysts for direct asymmetric three-component Mannich reactions of ketones, aldehydes and an amine (p-anisidine) have been developed. The corresponding β-amino carbonyl compounds (Mannich adducts) were obtained in good chemical yields and excellent enantio- and diastereoselectivities. The reaction conditions have been optimized by invoking ultrasonication and the influence of some structural moieties of the catalysts on the chemical yield and stereoselectivity of the Mannich products has been evaluated.
