    Polyketide Synthesis Using the Boron-Mediated, anti-Aldol Reactions of Lactate-Derived Ketones: Total Synthesis of (-)-ACRL Toxin IIIB
    摘要:
    The boron-mediated, anti-selective, aldol reactions of ketone 2 (and related derivatives) proceed with high levels of asymmetric induction, diastereoselectivities of up to 200:1 in favour of the aldol adducts 4 are obtained with achiral aldehydes and reagent control operates with chiral aldehydes. These lactate-derived ketones provide a versatile chiral auxiliary for the synthesis of beta-hydroxy carbonyl compounds. Oxidative removal of the auxiliary provides enantiomerically pure aldehydes 5, while reductive deoxygenation gives the corresponding ethyl ketones 6. This practical asymmetric methodology for generating anti-aldols is illustrated by an efficient total synthesis of (-)-ACRL toxin IIIB (7), which proceeds in 15 steps from 2 with 21% overall yield and 88% diastereoselectivity.

    混杂的底物结合说明了对映体纯的羟基酮和二醇的酶促立体和区域控制合成。
    摘要:
    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。

  • A Male-produced Aggregation Pheromone Blend Consisting of Alkanediols, Terpenoids, and an Aromatic Alcohol from the Cerambycid Beetle Megacyllene caryae
    作者:Emerson S. Lacey、Jardel A. Moreira、Jocelyn G. Millar、Lawrence M. Hanks

    日期:2008.3
    Bioassays conducted with a Y-tube olfactometer provided evidence that both sexes of the cerambycid beetle Megacyllene caryae (Gahan) were attracted to odor produced by males. Odor collected from male M. caryae contained eight male-specific compounds: a 10:1 blend of (2S,3R)- and (2R,3S)-2,3-hexanediols (representing 3.2 ± 1.3% of the total male-specific compounds), (S)-(−)-limonene (3.1 ± 1.7%), 2-phenylethanol (8.0 ± 2.4%), (−)-α-terpineol (10.0 ± 2.8%), nerol (2.1 ± 1.5%), neral (63.3 ± 7.3%), and geranial (8.8 ± 2.4%). Initial field bioassays determined that none of these compounds was attractive as a single component. Further field trials that used a subtractive bioassay strategy determined that both sexes were attracted to the complete blend of synthetic components, but the elimination of any one component resulted in a decline in trap captures. Blends that were missing (2S,3R)-2,3-hexanediol, (2R,3S)-2,3-hexanediol, or citral (a 1:1 mixture of neral and geranial) attracted no more beetles than did controls. A pheromone blend of this complexity, composed of alkanediols, terpenoids, and aromatic alcohols, is unprecedented for cerambycid species.
    使用Y管嗅觉计进行的生物测定提供了证据,表明杈甲虫Megacyllene caryae(Gahan)的雌雄个体均会被雄性产生的气味吸引。从雄性M. caryae收集的气味中发现了八种雄性特异性化合物:由(2S,3R)-和(2R,3S)-2,3-己二醇以10:1的比例混合(占总雄性特异性化合物的3.2 ± 1.3%)、(S)-(−)-柠檬烯(3.1 ± 1.7%)、2-苯乙醇(8.0 ± 2.4%)、(−)-α-松油醇(10.0 ± 2.8%)、宁罗尔(2.1 ± 1.5%)、尼拉尔(63.3 ± 7.3%)、和香茅醛(8.8 ± 2.4%)。最初的野外生物测定结果确定这些化合物在单一成分下并不具吸引力。进一步的野外试验采用减法生物测定策略,确定雌雄个体对合成成分的完整混合物存在吸引性,但移除任一成分都会导致捕捉数量下降。缺少(2S,3R)-2,3-己二醇、(2R,3S)-2,3-己二醇或香叶醛(宁罗尔和香茅醛的1:1混合物)的混合物吸引到的甲虫数量不比对照组多。如此复杂的信息素混合物,由烷二醇、萜类和芳香醇组成,在杈甲虫物种中是前所未有的。

    ketones (HK) and 1,2-diols are important building blocks for fine chemical synthesis. Here, we describe the R-selective 2,3-butanediol dehydrogenase from B. clausii DSM 8716T (BcBDH) that belongs to the metal-dependent medium chain dehydrogenases/reductases family (MDR) and catalyzes the selective asymmetric reduction of prochiral 1,2-diketones to the corresponding HK and, in some cases, the reduction
    α-羟基酮 (HK) 和 1,2-二醇是精细化学合成的重要组成部分。在这里,我们描述了来自B. clausii DSM 8716 T的R选择性 2,3-丁二醇脱氢酶(BcBDH),属于金属依赖性中链脱氢酶/还原酶家族 (MDR),催化前手性 1,2-二酮选择性不对称还原为相应的 HK,在某些情况下,将其还原为相应的 HK 1,2-二醇。脂肪族二酮,如 2,3-戊二酮、2,3-己二酮、5-甲基-2,3-己二酮、3,4-己二酮和 2,3-庚二酮都可以很好地转化。此外,令人惊讶的是,烷基苯基二羰基化合物,如 2-羟基-1-苯基丙-1-酮和苯基乙二醛是被接受的,而它们的具有两个苯基的衍生物不是底物。Mn 2+的补充(1 mM) 增加 BcBDH 在生物转化中的活性。此外,在酶膜反应器内仅使用少量 5-甲基-2-羟基-3-己酮将 5-甲基-2,3-己二酮生物催化还原为主要的 5-甲基-3-羟基-2-己酮是证明了。

    reductases in the production of α-hydroxy ketones and diols from vicinal diketones. The reactions have been carried out with pure enzymes and with an NADPH-regenerating system consisting of glucose-6-phosphate and glucose-6-phosphate dehydrogenase. To ascertain the regio and stereoselectivity of the reduction reactions catalyzed by the AKRs, we have separated and characterized the reaction products by means
    α-羟基酮被用作具有药用价值的化合物(例如抗抑郁药,HIV蛋白酶抑制剂和抗肿瘤药)的结构单元。它们可以通过酶或整个细胞在选定的底物(例如二酮)上的作用而获得。我们研究了几种由邻二酮生产α-羟基酮和二醇的真菌(AKR3C1,AKR5F和AKR5G)和人(AKR1B1和AKR1B10)醛-酮还原酶的对映体特异性。该反应已经用纯酶以及由葡萄糖-6-磷酸和葡萄糖-6-磷酸脱氢酶组成的NADPH再生系统进行了。确定区域通过AKR催化还原反应的立体选择性和立体选择性,我们已通过配备手性柱并连接到质谱仪作为检测器的气相色谱仪对反应产物进行了分离和表征。根据区域选择性和立体选择性,所研究的AKR可分为两组:其中一组显示出优先选择降低近端酮基,从而产生相应α-羟基酮的S-对映异构体。另一组赞成减少远端酮组并产生相应的R-对映体。所使用的三种AKR(AKR1B1,AKR1B10和AKR3C1)可以从乙酰丁香生
