    De Novo Synthesis of 2-Substituted syn-1,3-Diols via an Iterative Asymmetric Hydration Strategy
    摘要:
    The enantioselective syntheses of several protected 4-substituted syn-3,5-dihydroxy carboxylic esters have been achieved from the corresponding achiral (E,E)- or (E,Z)-1,3-dienoates. The route relies upon an enantio- and regioselective Sharpless dihydroxylation and a palladium-catalyzed reduction to form gamma-substituted delta-hydroxy-1-enoates. The resulting delta-hydroxy-1-enoates are subsequently converted into benzylidene-protected 4-substituted syn-3,5-dihydroxy carboxylic esters in one step. The benzylidene-protected 3,5-dihydroxy carboxylic esters are produced in good overall yields (20-54%) and high enantiomeric excess (73- 97% ee).

  • Silylene-Mediated Polarity Reversal of Dienoates: Additions of Dienoates to Aldehydes at the δ-Position To Form <i>trans</i>-Dioxasilacyclononenes

    trans-dioxasilacyclononenes as single stereoisomers. This reaction, which converts the δ-position of the unsaturated carbonyl compound into a nucleophilic center, represents an inversion of polarity from the normal pattern of reactivity. The stereospecificity of the reaction suggests that the addition to aldehydes occurred through a closed, chairlike six-membered transition state. This reaction can be
    亚甲硅烷向 α,β,γ,δ-不饱和羰基化合物的转移产生了氧杂硅杂环戊烯,这些杂硅杂环戊烯经过与醛的热加成以产生作为单一立体异构体的反式二氧杂硅杂环壬烯。该反应将不饱和羰基化合物的 δ 位转化为亲核中心,代表了正常反应模式的极性反转。该反应的立体特异性表明醛的加成是通过一个封闭的、椅子状的六元过渡态发生的。通过使用手性助剂来控制氧硅杂环戊烯的形成,该反应可用于制备对映体纯材料。所得反式环烯烃的官能化完全立体选择性地发生。
  • A New Directing Mode for Singlet Oxygen Ene Reactions: The Vinylogous Gem Effect Enables a <sup>1</sup>O<sub>2</sub> Domino Ene/[4 + 2] Process
    作者:Axel G. Griesbeck、Alan de Kiff

    日期:2013.5.3
    The singlet oxygen reactions of 4-methyl-2,4-hexadienoates E,E- and E,Z-4 proceed in a highly mode selective and regioselective domino process. The initial product is the allylic hydroperoxide 5 directed by a vinylogous gem effect. The subsequent 1O2 [4 + 2] cycloaddition delivers a 3:2 diastereoisomeric mixture of 1,2-dioxanes 8 in a one-pot process. The identical protocol delivers from the more reactive
