  Lipase-catalyzed resolution of p-menthan-3-ols monoterpenes: preparation of the enantiomer-enriched forms of menthol, isopulegol, trans- and cis-piperitol, and cis-isopiperitenol

  摘要：

  A study on the enzymic resolution of the most common p-menthan-3-ol monoterpene isomers is described. Enantio-enriched alcohols 1, 5, 10, 11 and 12 are obtained by means of the lipase-mediated kinetic acetylation of the corresponding racemic materials. The stereochemical aspects of the enzymic process have been investigated. We found that the structural features of the starting p-menthan-3-ol as well as the kind of lipase used, impacted strongly on the enantioselectivity of the resolution. The potentialities of this approach for preparative purposes are discussed. (C) 2003 Elsevier Ltd. All rights reserved.

  The 13C NMR behaviour of 21 p‐menthanic terpene bearing an oxygenated function (alcohol, ketone, acetate) was examined in the presence of a chiral lanthanide shift reagent (Yb(hfc)3). For each monocyclic compound, we measured the lanthanide‐induced shift (LIS) on the signals of the carbons and the splitting of signals allowing the enantiomeric differentiation. Some general features were found about

  在手性镧系元素位移试剂 (Yb(hfc)3) 存在下，研究了具有氧化功能（醇、酮、乙酸盐）的 21 对薄荷烷萜烯的 13C NMR 行为。对于每个单环化合物，我们测量了碳信号上的镧系元素诱导位移（LIS）和允许对映体分化的信号分裂。发现了关于它们的 LIS 行为的一些一般特征：实验数据为香芹酮类化合物和薄荷酮类化合物建立了不同的模式。对于每种化合物的光谱中的大部分信号，观察到对映体分裂。在醇和乙酸酯的情况下，讨论了异丙基（烯）的相对立体化学（顺式与反式）和结合功能的影响。版权所有 © 2008 John Wiley & Sons, Ltd.
• Isolation, structural assignment and insecticidal activity of (−)-(1S,2R,3R,4S)-1,2-epoxy-1-methyl-4-(1-methylethyl)-cyclohex-3-yl acetate, a natural product from Minthostachys tomentosa

  (-)-(1S,2R,3R,4S)-1,2-Epoxy-1-methyl-4-(1-methylethyl)-cyclohex-3-yl acetate has previously been identified as the active compound of Minthostachys tomentosa responsible for the insecticidal activity against Oncopeltus fasciatus. Its structure was initially assigned on the basis of spectral data. In order to confirm the structure and to define the stereochemistry, stereoselective synthesis of its enantiomer, (+)-(1R,2S,3S,3R)-1,2-epoxy-1-methyl-4-(1-methylethyl)-cyclohex-3-yl acetate, starting from (R)-(-)piperitone, was carried out using a Sharpless reaction as the key step. The natural product is dextro-rotatory while the synthetic product is levo-rotatory. Measurements of insecticidal activities of the different steroisomers revealed that only the natural product is active. (C) 2001 Elsevier Science Ltd. All rights reserved.

  (-)-(1S,2R,3R,4S)-1,2-环氧-1-甲基-4-(1-甲基乙基)-环己-3-基醋酸酯已被鉴定为保护植物 Against Oncopeltus fasciatus 的斑须蝇植株植物活性成分活性分子。其结构最初是基于光谱数据确定的。为了确认结构并确定立体化学，以 (R)-(-) 芥子酮为起始原料，通过使用Sharpless反应作为关键步骤，成功地进行了其对映体 (+)-(1R,2S,3S,4R)-1,2-环氧-1-甲基-4-(1-甲基乙基)-环己-3-基醋酸酯的立体选择性合成。天然产物是右旋的，而合成产物是左旋的。对不同立体异构体的杀虫活性的测量表明，只有天然产物是具有活性的。© 2001 Elsevier Science Ltd. 保留所有权利。
