  • First enantioselective synthesis and determination of the absolute configuration of natural (+)-dehydro-β-monocyclonerolidol
    作者:Elie Palombo、Gérard Audran、Honoré Monti
    DOI:10.1016/s0040-4039(03)01562-4
    日期:2003.8
    The enantioselective synthesis and determination of the absolute configuration of (+)-dehydro-β-monocyclonerolidol, a natural product isolated from the liverwort P. subobtusa, has been achieved starting from (+)-karahana lactone as an enantiopure building block. Furthermore, the methodology applied provided a new approach towards the known (+)-γ-cyclohomocitral, a key intermediate in the sequence,
    从(+)-卡拉汉纳内酯作为对映纯结构单元开始,已经实现了从(+)-卡拉汉纳内酯分离的天然产物(+)-脱氢-β-单环神经醇的对映体选择性合成和绝对构型的确定。此外,所采用的方法为已知的(+)-γ-环同源物(序列中的关键中间体)和天然的(+)-pallescensone提供了新的方法。
  • Lipase-mediated resolution of the hydroxy-cyclogeraniol isomers: application to the synthesis of the enantiomers of karahana lactone, karahana ether, crocusatin C and γ-cyclogeraniol
    作者:Stefano Serra、Francesco G. Gatti、Claudio Fuganti
    DOI:10.1016/j.tetasy.2009.05.013
    日期:2009.6
    study on the lipase PS-mediated resolution of different hydroxy-geraniol isomers is reported. A number of α-, β- and γ-isomers bearing a 2-, 3- or 4-hydroxy functional group were synthesised regioselectively and then submitted to the lipase-mediated kinetic acetylation. The latter experiments showed that the 2-hydroxy isomers 4, 5 and 14 (α, γ and β, respectively) as well as cis-3-hydroxy α-cyclogeraniol
    报道了对脂肪酶PS介导的不同羟基香叶醇异构体拆分的综合研究。选择性地合成许多带有2-,3-或4-羟基官能团的α-,β-和γ-异构体,然后进行脂肪酶介导的动力学乙酰化。后者实验表明,2-羟基异构体4,5和14(α,γ分别和β),以及顺式-3-羟基α-cyclogeraniol 7和顺式-4-羟基γ-cyclogeraniol 10可以很容易地通过此过程解决。这些化合物主要部分的对映体纯度通过重结晶而提高,所得对映体二醇被用作合成天然萜类化合物卡拉汉内酯,卡拉汉醚和番红花素C的组成部分,并用于制备合成中间体γ-环香叶醇。二醇的对映异构体的绝对构型7,10,14和19通过用已知化合物的化学相关性来确定40,41,39和41分别。
  • Enantioselective Synthesis of (+)-Ricciocarpin A Using an Auxiliary Hydroxyl Group and a Diastereofacial Selectivity Based Methodology
    作者:Gérard Audran、Elie Palombo、Honoré Monti
    DOI:10.1055/s-2005-871932
    日期:——
    An enantioselective synthesis of (+)-ricciocarpin A is described starting from (+)-karahana lactone as an enantiopure building block. This synthesis involves a stereofacially directed diastereoselective hydroboration for the installation of the required stereogenic center, and the efficient conversion of an intermediate hydroxyaldehyde to the one-carbon homologated cyanide, using the mild formation
    描述了从 (+)-karahana 内酯作为对映体纯构建块开始的 (+)-ricciocarpin A 的对映选择性合成。该合成涉及立体定向的非对映选择性硼氢化反应以安装所需的立体中心,以及中间体羟基醛有效转化为一碳同系氰化物,使用温和的氰醇形成,然后是一锅两步巴顿-McCombie 羟基部分的双脱氧序列。
  • First Enantioselective Synthesis and Absolute Stereochemistry Assignment of New Monoterpene Aldehyde-Esters fromBupleurum gibraltaricum
    作者:Paul Brémond、Gérard Audran、Thierry Juspin、Honoré Monti
    DOI:10.1002/ejoc.200601080
    日期:2007.6
    The first enantioselective synthesis of two new monoterpene aldehyde-esters from Bupleurum gibraltaricum, starting from an enantiopure building block, is described. The key step is a strictly controlled esterification to afford the somewhat unstable target compounds. The previously unknown absolute stereochemistries of these natural products have been established.(© Wiley-VCH Verlag GmbH & Co. KGaA
    描述了从直布罗陀柴胡 (Bupleurum gibraltaricum) 中首次对映选择性合成两种新的单萜醛酯,从对映体纯构建块开始。关键步骤是严格控制酯化,以提供有些不稳定的目标化合物。这些天然产物以前未知的绝对立体化学已经建立。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
  • First Enantioselective Synthesis and Absolute Stereochemistry Assignment of New Monocyclic Sesquiterpenes from <i>Artemisia </i><i>c</i><i>hamaemelifolia</i>
    作者:Jean-Pierre Uttaro、Gérard Audran、Elie Palombo、Honoré Monti
    DOI:10.1021/jo034424y
    日期:2003.6.1
    We herein report the first enantioselective synthesis of two new monocyclic sesquiterpenes from Artemisia chamaemelifolia starting from an enantiopure building block. The key feature of the present approach is to allow complete control of all the stereogenic centers present in the natural products and to elucidate their absolute stereochemistry, which to date is unknown.
    我们在此报告了从对映纯构件开始的来自蒿蒿的两个新的单环倍半萜的第一次对映选择性合成。本方法的关键特征是允许完全控制天然产物中存在的所有立体异构中心,并阐明其绝对立体化学,这迄今为止是未知的。
