  • Stereoselective synthesis of chiral δ-lactones <i>via</i> an engineered carbonyl reductase
    作者:Tao Wang、Xiao-Yan Zhang、Yu-Cong Zheng、Yun-Peng Bai
    DOI:10.1039/d1cc04542c
    日期:——
    A carbonyl reductase variant, SmCRM5, from Serratia marcescens was obtained through structure-guided directed evolution. The variant showed improved specific activity (U mg−1) towards most of the 16 tested substrates and gave high stereoselectivities of up to 99% in the asymmetric synthesis of 13 γ-/δ-lactones. In particular, SmCRM5 showed a 13.8-fold higher specific activity towards the model substrate
    来自粘质沙雷氏菌的羰基还原酶变体Sm CR M5是通过结构引导的定向进化获得的。该变体对 16 种测试底物中的大多数表现出改善的比活性 (U mg -1 ),并在 13 种 γ-/δ-内酯的不对称合成中提供高达 99% 的高立体选择性。特别是,SmCR M5对模型底物(即5-氧代癸酸)的比活性高出 13.8 倍,并在 99% ee 中产生 ( R )-δ-癸内酯,时空产率 (STY) 为 301 g L -1 d -1. 六种δ-内酯的高收率和高对映体纯度的制备表明这些高附加值化学品的生物催化合成是可行的,为贵金属催化提供了一种具有成本效益的绿色替代品。

    (R)-6-Heptyltetrahydropyran-2-one and its S-enantiomer were synthesized via chiral resolution of (±)-1-undecen-4-ol by (R)-3a-allyl-3,3a,4,5-tetrahydro-2H-cyclopenta[b]furan (CPF). The R-enantiomer has sophisticated strong, fruity flavor, while the ­flavor of the S-enantiomer is soft and sweet, similar to apricot.

  • Cascade Biotransformations via Enantioselective Reduction, Oxidation, and Hydrolysis: Preparation of (<i>R</i>)-δ-Lactones from 2-Alkylidenecyclopentanones
    作者:Ji Liu、Zhi Li
    DOI:10.1021/cs400101v
    日期:2013.5.3
    cascade biotransformation involving enantioselective reduction of a C═C double bond, Baeyer–Villiger oxidation, and lactone hydrolysis was developed as a green and sustainable tool for synthesizing enantiopure δ-lactones. One-pot cascade biotransformations were achieved with Acinetobacter sp. RS1 containing a novel enantioselective reductase and an enantioselective lactone hydrolase and Escherichia coli
    作为涉及绿色和可持续的合成对映纯δ-内酯的工具,首次涉及级联生物转化涉及C═C双键的对映选择性还原,Baeyer-Villiger氧化和内酯水解。不动杆菌属一锅级联生物转化。RS1含有新颖的对映选择性还原酶和对映体选择性内酯水解酶和大肠杆菌共表达的环己酮单加氧酶和葡糖脱氢酶,转换容易获得的2- alkylidenecyclopentanones 1 - 2成相应的有价值的香精香料([R)-δ-内酯5 - 6在高ee中。一锅法合成优于报道的两步法制备。该概念对于开发其他包含C═C双键的底物的氧化还原级联反应很有用。
  • Asymmetric bioreduction of keto groups of 4- and 5-Oxodecanoic acids/esters with a new carbonyl reductase
    作者:Chao Zhang、Jiang Pan、Chun-Xiu Li、Yun-Peng Bai、Jian-He Xu

    Escherichia coli. SmCR could catalyze the asymmetric reduction of long-chain keto acids/esters containing remote carbonyl groups, such as 4-oxo- and 5-oxodecanoic acids, yielding chiral γ- and δ-decalactones with high enantiopurity (up to 99% ee). This is the first report of enzymatic synthesis of (R)-γ- and (R)-δ-decalactones starting from γ-, δ-keto acids using free enzymes.
    来自粘质沙雷氏菌的新型羰基还原酶,Sm CR,已成功克隆并在大肠杆菌中过表达。Sm CR可以催化含有远端羰基的长链酮酸/酯(例如4-氧代和5-氧代十二酸)的不对称还原,产生具有高对映体纯度(高达99%ee)的手性γ-和δ-癸内酯。。这是关于使用游离酶从γ-,δ-酮酸开始酶促合成(R)-γ-和(R)-δ-十内酯的第一个报道。
