  • The First Synthesis of Geranyllinalool Enantiomers
    作者:Aleš Svatoš、Klára Urbanová、Irena Valterová
    DOI:10.1135/cccc20020083
    日期:——

    (3R)-(-)-Geranyllinalool and its (3S)-(+)-isomer were synthesized in 7 steps starting from both enantiomers of citramalic acid and geranyl bromide. The synthetic sequence established the absolute configurations of naturally occurring geranyllinalools for the first time.

  • Re‐Investigation of Hydration Potential of <i>Rhodococcus</i> Whole‐Cell Biocatalysts towards Michael Acceptors

    has been reported to hydrate various Michael acceptors leading to chiral alcohols. This study aimed at the in‐depth re‐investigation of the hydration potential of Rhodococcus whole‐cells towards Michael acceptors. Here, two concurrent effects responsible for the hydration reaction were found: while the majority of substrates was hydrated in an oxygen‐independent manner by amino‐acid catalysis, an enzyme‐catalysed
    以水为底物的立体选择性迈克尔加成物的实施仍然是经典化学方法的主要挑战。受自然界以高选择性和高效率进行这种有吸引力的反应的能力启发,对水合酶(EC 4.2.1.x)实现选择性加水的兴趣正在稳步上升。革兰氏阳性细菌红球菌属(Rhodococcus)被称为生物催化强国,据报道会水合各种迈克尔受体,从而导致手性醇。这项研究旨在深入研究红球菌的水合作用潜力对迈克尔受体的整个细胞。在这里,发现了两个同时引起水合反应的作用:虽然大多数底物通过氨基酸催化以不依赖氧的方式水合,但酶催化的水除了(E)-4-羟基-3-甲基丁酸外-2-烯酸被证明是依赖于氧气的。18 O 2标记研究表明,产品中未掺入18 O 2。因此,发现了一种新颖的O 2依赖性水合酶,与迄今为止所有表征的水合酶不同。
  • Enantioselective Synthesis of 2-Methyl-2-hydroxy-.gamma.-butyrolactone and Its Application in the Asymmetric Synthesis of Frontalin and Mevalonolactone
    作者:Franklin A. Davis、G. Venkat Reddy、Bang-Chi Chen、Anil Kumar、M. Serajul Haque

    日期:1995.9
    The asymmetric hydroxylation of the enolates of fully substituted acyclic ester 8 and lactone 10 with (camphorylsulfonyl)oxaziridines 1a-c was studied. The stereoselectivities of the tertiary alpha-hydroxy carbonyl products were highly dependent on the enolate structure, the oxidizing reagents, and the reaction conditions. While high diastereoselectivity (up to 94%) was obtained for enolates of fully substituted menthol ester 8 with substoichiometric amounts of oxaziridine 1a, the yields were unsatisfactory. On the other hand, the enantioselective alpha-hydroxylation of the sodium enolate of 2-methyl-gamma-butyrolactone (10) with [(8,8-dimethoxycamphoryl)sulfonyl]oxaziridine (1c) afforded alpha-hydroxy lactone 11a in 70% yield and 84% ee. The enantiomeric excess was improved to > 93% ee by crystallization of the corresponding benzoyl ester 11c. The utility of both enantiomers of 11c were demonstrated in the formal asymmetric syntheses of the pheromone, (1S,5R)-(-)-frontalin (13) and in the asymmetric synthesis of (R)-(-)-mevalonolactone (20).
