  • 1,2-Stereoinduction in Radical Reactions: Stereoselective Synthesis of 2-Alkyl-3-hydroxybutanoates
    作者:Michel Bulliard、Margareta Zehnder、Bernd Giese
    DOI:10.1002/hlca.19910740722
    日期:1991.10.30
    Radical addition to 2-cyclohexyl-5-methylidene-6-methyl-1,3-dioxan-4-one (2) affords stereoselectively 5,6-trans-products trans-3. The size of the radical has no influence on the selectivity. These trans-acetals are converted into threo-3-hydroxy-butanoates 4. Methyl 2-methylidene-3-[(tert-butyl)diphenylsilyloxy]butanoate (5), treated under the same conditions, leads mainly to the erythro-isomer of
    自由基加成到2-环己基-5-亚甲基-6-甲基-1,3-二恶烷-4-酮(2)立体选择性地得到5,6-反式-products反式- 3。自由基的大小对选择性没有影响。这些反式-缩醛被转化为苏--3-羟基丁酸酯4。在相同条件下处理的2-亚甲基-3-[(叔丁基)二苯基甲硅烷氧基]丁酸甲酯(5)在脱保护后主要导致4的赤型异构体。观察到自由基的空间庞大性的影响。讨论了反应的立体化学过程。
  • 1,2-Stereoinduction in Radicals and Anions: A comparison between hydrogen abstraction and protonation
    作者:Peter Erdmann、Jörg Schäfer、Ronald Springer、Heinz-Georg Zeitz、Bernd Giese
    DOI:10.1002/hlca.19920750219
    日期:1992.3.18
    Chiral enolates 5 and 10, generated by radical addition and subsequent reduction, show diastereofacial selectivity during protonation. In the presence of substituted amines, diastereoselectivity is enhanced and becomes comparable to radical stereoselection. Diastereoselectivities up to 99:1 and yields up to 90% are reached.
    通过自由基加成和随后的还原生成的手性烯醇盐5和10在质子化过程中显示出非对面选择性。在取代胺的存在下,非对映选择性增强,并且与自由基立体选择相当。非对映选择性高达99:1,产率高达90%。
  • Acyclic Stereocontrol of Free Radical Reactions Involving Alkyl 2-(1-Hydroxyalkyl)propenoates
    作者:FW Eastwood、RD Mifsud、P Perlmutter
    DOI:10.1071/ch9942187
    日期:——

    The addition of cyclohexyl and t-butyl free radicals to silylated derivatives of alkyl 2-(1-hydroxyalkyl) propenoates was found to be stereoselective . In the case of the cyclohexyl radical the stereoselectivity was dependent upon the conditions used to generate the free radical and to quench the intermediate. Stereoselectivity in additions of the t-butyl radical was found to be temperature-dependent. In all cases stereoselectivity increased as the steric bulk of the group attached to the carbinol oxygen increased. A simple model which accounts for the stereoselectivity is proposed.

    研究发现,环己基和叔丁基自由基与 2-(1-羟基烷基)丙烯酸烷基硅烷化衍生物的加成具有立体选择性。环己基自由基的立体选择性取决于生成自由基和淬灭中间体的条件。研究发现,t-丁基自由基加成的立体选择性与温度有关。在所有情况下,立体选择性都会随着连接到羰基氧上的基团立体体积的增加而增加。提出了一个解释立体选择性的简单模型。
  • Studies Towards Total Synthesis of Antillatoxin: Indium-mediated Allylation Reaction of Carbonyl Compounds with Secondary Allylic Bromide in Aqueous Media
    作者:Teck-Peng Loh、Hong-Yan Song
    DOI:10.1055/s-2002-35606
    日期:——
    We have established a new reaction condition for the indium-mediated allylation of an unreactive secondary allylic bromide with aldehydes in aqueous media to afford the corresponding homoallylic alcohols in high yields and syn diastereoselectivity. Furthermore, it has provided an easy entry to the key intermediate for the total synthesis of antillatoxin under mild and environment profitable conditions
    我们已经建立了一种新的反应条件,用于在水性介质中将惰性仲烯丙基溴与醛进行铟介导的烯丙基化,以高产率和顺式非对映选择性提供相应的高烯丙醇。此外,它为在温和和环境有利的条件下全合成抗霉毒素提供了一个容易进入的关键中间体。
