    描述了可控制衍生自1,3-二恶烷-5-酮(4)的烯醇酯在醛醇缩合反应中立体选择性的方法。原位生成的硼烯醇化物与苯甲醛反应,以高产率选择性地产生相应的抗羟醛(反∶syn比例高达96:4)。烯醇锂仅在α位分支的醛才具有较高的抗选择性。使用具有一般结构PhCH(Me)N(Li)R的手性锂酰胺碱,对映体过量C可以高效地完成C(S)对称二恶烷(例如4b)的对映选择性去质子化反应(9,10)如果R基团足够大(例如,R =金刚烷基)或被氟化(例如,R = CH 2 CF 3)。二恶烷酮硼和烯醇锂易于与甘油醛衍生物(19)反应,生成受保护的酮己糖(20和21)。

    摘要:
    描述了通过在 2,2-二甲基-1,3-二恶烷-5-one(二恶烷酮)的 α 和 α' 位置进行的两个羟醛反应序列合成高级碳水化合物的方法。如前所述,第一个羟醛反应在有机催化条件下(脯氨酸催化)运行良好,然后是保护羟基,使用过量的 LDA 使所得化合物去质子化,以及第二个羟醛添加。这一系列反应产生了具有直链碳骨架的化合物,每个碳上都有一个基于氧的官能团。大多数组都受到保护。6-C-苯基-D-甘油-D-allo-己基吡喃糖和D-赤型-D-allooctopyranose 的短合成说明了该策略的效用(© Wiley-VCH Verlag GmbH & Co.

  • Stereoselective Synthesis of Protected Ketohexoses via Aldol Reaction of Chiral Dioxanone Enolate
    作者:Marek Majewski、Pawel Nowak
    DOI:10.1055/s-1999-2862
    日期:1999.9
    Lithium and boron enolates of 2,2-dialkyl-1,3-dioxa-5-ones react with aldehydes to give aldol products in high diastereoselectivity and, when chiral lithium enolates are generated using optically pure chiral lithium amide bases, in high enantioselectivity. Dioxanone lithium enolates react readily with protected glyceraldehyde affording protected ketohexoses in high diastereo- and enantiomeric purity.

    A direct de novo synthesis of ketoses and amino sugars by amino acid-catalyzed asymmetric aldol, Mannich and Michael reactions with dihydroxyacetone phosphate mimics as donors is presented. Proline, proline derivatives and thiazolidine-4-carboxylic acids catalyzed the asymmetric assembly of keto sugars and amino sugars in high yield with up to >99% ee.

    Prolinamido-glycosides, water-compatible organocatalysts, are capable of catalyzing the stereoselective aldol reaction in aqueous media. The aldol reaction of 2,2-dimethyl-1,3-dioxan-5-one with aldehydo sugars in the isopropylidene form gave ketoses stereoselectively. The stereochemistry of these aldol reactions has been investigated in terms of the influence of conformational effects, and the results demonstrate

  • Dihydroxyacetone Variants in the Organocatalytic Construction of Carbohydrates:  Mimicking Tagatose and Fuculose Aldolases
    作者:Jeff T. Suri、Susumu Mitsumori、Klaus Albertshofer、Fujie Tanaka、Carlos F. Barbas
    DOI:10.1021/jo0602017
    日期:2006.5.1
    Dihydroxyacetone variants have been explored as donors in organocatalytic aldol reactions with various aldehyde and ketone acceptors. The protected form of dihydroxyacetone that was chosen for in-depth study was 2,2-dimethyl-1,3-dioxan-5-one, 1. Among the catalysts surveyed here, proline proved to be superior in terms of yield and stereoselectivities in the construction of various carbohydrate scaffolds. In a fashion analogous to aldolase enzymes, the de novo preparation of L-ribulose, L-lyxose, D-ribose, D-tagatose, 1-amino-1-deoxy-D-lyxitol, and other carbohydrates was accomplished via the use of 1 and proline. In reactions using 2,2-dimethyl-1,3-dioxan-5-one 1 as a donor, (S)-proline can be used as a functional mimic of tagatose aldolase, whereas (R)-proline can be regarded as an organocatalytic mimic of fuculose aldolase.
  • Mimicking Dihydroxy Acetone Phosphate-Utilizing Aldolases through Organocatalysis:  A Facile Route to Carbohydrates and Aminosugars
    作者:Jeff T. Suri、Dhevalapally B. Ramachary、Carlos F. Barbas
    DOI:10.1021/ol0502533
    日期:2005.3.1
    A practical and environmentally friendly organocatalytic strategy designed to mimic the DHAP aldolases has been developed and shown to be effective in the preparation of carbohydrates and aminosugars. (S)-Proline and (S)-2-pyrrolidine-tetrazole catalyzed the aldol reaction between dihydroxy acetone variants such as 1,3-dioxan-5-one and 2,2-dimethyl-1,3-dioxan-5-one with aldehydes to give the corresponding polyols in good yields with very high ees.
