  Design of Organocatalysts for Asymmetric Direct Syn-Aldol Reactions

  摘要：

  Two new organocatalysts 3a and 3b, derived from L-leucine and (S)-beta-amino alcohols that were prepared from L-valine, were designed and afforded the direct syn-aldol reactions of a wide scope of aldehydes with various ketones with an excellent diastereomeric ratio of up to >20/1 and enantioselectivities of up to 99% ee.

  The catalytic promiscuity of pepsin from porcine gastric mucous was observed in catalysis of the direct asymmetric aldol reactions of aromatic aldehydes with acetones, which were substituted by hydroxy-, dihydroxy-, methoxy- and benzyloxy- for the synthesis of diol compounds in acetonitrile. This biocatalysis was also applicable to the aldol reactions of cyclic or hetereocyclic ketones with aromatic

  anti-1,2-amino alcohols and syn-1,2-diols through direct asymmetric Mannich, Mannich-type, and aldol reactions involving unmodified α-hydroxyketones in reactions catalyzed by primary amine-containing amino acids. These reactions exploit (Z)-enamines of α-hydroxyketones in their bond-forming transition states. This study compliments and extends our bioorganic approach to asymmetric synthesis in these two

  手性 1,2-氨基醇和 1,2-二醇是在大量天然和生物活性分子中发现的常见结构基序。已经报道了使用基于金属的策略有效对映选择性合成含有顺-或反-1,2-氨基醇和1,2-二醇的酮。然而，迄今为止，涉及有机催化的方法仅限于合成 1,2-氨基醇和反 1,2-二醇。在此，我们公开了通过直接不对称曼尼希、曼尼希型和羟醛反应（涉及未修饰的 α-羟基酮在伯胺催化的反应中）制备高度对映体富集的抗 1,2-氨基醇和合成 1,2-二醇的简单有效途径-含氨基酸。这些反应利用处于成键过渡态的 α-羟基酮的 (Z)-烯胺。这项研究补充并扩展了我们在这两种多功能合成子类中进行不对称合成的生物有机方法。值得注意的是，这些反应是实用的，耐受湿溶剂，并且...

  We present herein simple primary-tertiary diamine-Bronsted acid conjugates that catalyze both syn- and anti-adol reactions of dihydroxyacetones (DHAs) with high diastereoselectivities and enantioselectivities. This type of organocatalysts functionally mimics all four DHA aldolases, namely L-fuculose-1-phosphate aldolase, D-tagatose-1,6-diphosphate aldolase, D-fructose-1,6-diphosphate aldolase, and L-rhamnulose-1-phosphate aldolase.
• Chiral amine organocatalysts for the syn-aldol reaction involving substituted benzaldehydes and hydroxyacetone

  A new series of cyclohexanediamine organocatalysts that contain the primary amine functionality has been designed, synthesized and tested as catalysts for the asymmetric aldol reaction involving hydroxyacetone and a variety of substituted benzaldehydes. High enantioselectivites and diasteroselectivites were obtained using catalyst la for these reactions. A key step in this reaction for the formation of the syn-product is the formation of a stable intramolecular hydrogen bonded Z-enamine isomer, which in addition to the steric bulk of the catalyst, serve to dictate the course of the stereochemical outcome of the reaction.
