  • Regio- and Stereoselective Reduction of Diketones and Oxidation of Diols by Biocatalytic Hydrogen Transfer
    作者:Klaus Edegger、Wolfgang Stampfer、Birgit Seisser、Kurt Faber、Sandra F. Mayer、Reinhold Oehrlein、Andreas Hafner、Wolfgang Kroutil
    DOI:10.1002/ejoc.200500839
    日期:2006.4
    The asymmetric reduction of symmetrical and nonsymmetrical diketones as well as the stereoselective oxidation of various diols by biocatalytic hydrogen transfer was investigated by employing lyophilized cells of Rhodococcus ruber DSM 44541 containing alcohol dehydrogense ADH-‘A’. Symmetrical and nonsymmetrical diketones at the (ω-1)- and (ω-2)-positions are reduced to the Prelog product with high stereopreference
    通过使用含有乙醇脱氢 ADH-'A' 的红球菌 DSM 44541 的冻干细胞,研究了对称和非对称二酮的不对称还原以及通过生物催化氢转移对各种二醇的立体选择性氧化。(ω-1)-和 (ω-2)-位置的对称和非对称二酮被还原为具有高立体偏好的 Prelog 产物,而空间上要求更高的酮部分,例如 (ω-3)-位置的那些,保持不变。对于氧化模式,实现了伯醇和仲醇之间的区别,并且在(ω-1)-和(ω-2)-位的(S)构型的仲醇被优先氧化。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
  • Structure Elucidation and Synthesis of Dioxolanes Emitted by Two <i>Triatoma</i> Species (Hemiptera: Reduviidae)

    5S*)-4-ethyl-5-methyl-2-(2-methylpropyl)-1,3-dioxolane (5) (trace component). Syntheses of optically active 1 and 3 were carried out by reacting pure enantiomers of 2,3-pentanediol with 3-pentanone or 2-methylpropanal. The preparation of pure stereoisomers of 2,3-pentanediol involved a novel key step for the synthesis of secondary alcohols: the reduction of a carboxylic ester by means of DIBAH and in situ alkylation
    通过SPME-GC / MS分析了两个真实的Triatominae亚科的臭虫,巴西的Triatoma brasiliensis和Triatoma infestans的后胸骨挥发物。发现了两组新的天然产物:(4 S,5 S)-和(4 R,5 R)-2,2,2,4-三乙基-5-甲基-1,3-二氧戊环(1)(主要成分)和(4 S *,5 S *)-2,4-二乙基-2,5-二甲基-1,3-二氧戊环(2)(痕量组分),(2 R / S,4 S,5 S)-以及(2 R / S,4 R,5 R)-4-乙基-5-甲基-2-(1-甲基乙基)-1,3-二氧戊环(3)(次要成分),(2 R / S,4 S *,5 S *)-4 -乙基-5-甲基-2-(1-甲基丙基)-1,3-二氧戊环(4)(痕量组分)和(2 R / S,4 S *,5 S *)-4-乙基-5-甲基-2-(2-甲基丙基)-1,3-二氧戊环(5)(
  • Diastereoselectivity of the mercuration of acyclic allylic alcohols
    作者:Bernd Giese、Dieter Bartmann
    DOI:10.1016/s0040-4039(00)98432-6
    日期:1985.1
    The diastereoselectivity of the mercuration of acyclic alkenes can be reversed by changing the substituent in the allylic position; with alcohols the erythro isomers and with esters or hemiacetals the threo isomers and are formed predominantly (Table I).
    通过改变烯丙基位置上的取代基,可以逆转无环烯烃的非对映选择性。与醇形成赤型异构体,与酯或半缩醛形成苏式异构体,主要形成(表I)。
  • Hydroxy-directed regio-diastereoselective ene reaction of singlet oxygen with chiral allylic alcohols
    作者:Waldemar Adam、Bernd Nestler
    DOI:10.1021/ja00065a013
    日期:1993.6
    The photooxygenation of chiral allylic alcohols 1a, (Z)-1f-k, ethers 1b-d, and acetate 1e gave the corresponding hydroperoxy homoallylic alcohols and derivatives 2 through the ene reaction with singlet oxygen. While the reaction of the acetate 1e proceeded erythro-diastereoselectively as a result of the classical cis effect, for the allylic alcohols 1a and (Z)-1f-k, in which an alkyl group is located
    手性烯丙醇 1a、(Z)-1f-k、醚 1b-d 和乙酸酯 1e 的光氧化反应通过与单线态氧的烯反应得到相应的氢过氧高烯丙醇和衍生物 2。由于经典的顺式效应,乙酸酯 1e 的反应以赤型非对映选择性进行,对于烯丙醇 1a 和 (Z)-1f-k,其中烷基位于带羟基的取代基的顺式,高观察到threo选择性。这一发现可以通过立体中心的亲核羟基官能团与进入的亲电子单线态氧亲烯体的配位来解释
  • Promiscuous Substrate Binding Explains the Enzymatic Stereo- and Regiocontrolled Synthesis of Enantiopure Hydroxy Ketones and Diols
    作者:Marcela Kurina-Sanz、Fabricio R. Bisogno、Iván Lavandera、Alejandro A. Orden、Vicente Gotor
    DOI:10.1002/adsc.200900218
    日期:2009.8
    Regio- and stereoselective reductions of several diketones to afford enantiopure hydroxy ketones or diols were accomplished using isolated alcohol dehydrogenases (ADHs). Results could be rationalised taking into account different (promiscuous) substrate-binding modes in the active site of the enzyme. Furthermore, interesting natural cyclic diketones were also reduced with high regio- and stereoselectivity
    使用分离的醇脱氢酶(ADHs)可实现几种二酮的区域和立体选择性还原,得到对映纯的羟基酮或二醇。考虑到酶活性位点中不同(混杂)的底物结合模式,可以合理化结果。此外,有趣的天然环状二酮也以高的区域选择性和立体选择性被还原。由于这些ADH催化过程的准不可逆性,通过使用少量过量的氢供体(2-丙醇)减少了本研究中使用的1,2-和1,3-二酮。因此,使用较少量的共衬底,可以容易地实现放大。
