  • Hydrogen borrowing catalysis using 1° and 2° alcohols: Investigation and scope leading to α and β branched products
    作者:James R. Frost、Choon Boon Cheong、Wasim M. Akhtar、Dimitri F.J. Caputo、Kirsten E. Christensen、Neil G. Stevenson、Timothy J. Donohoe

    variety of ketones using 1° or 2° alcohols under hydrogen borrowing catalysis is described. Initial research focused on the α-alkylation of cyclopropyl ketones with higher 1° alcohols (i.e. larger than MeOH), leading to the formation of α-branched products. Our search for additional substrates with which to explore this chemistry led us to discover that di-ortho-substituted aryl ketones were also privileged
    描述了在氢借位催化下使用1°或2°醇对各种酮进行的烷基化。最初的研究集中在环丙酮与更高的1°醇(即大于MeOH)的α-烷基化反应上,导致形成α-支化产物。我们通过寻找其他底物来探索这种化学反应,使我们发现,二邻位取代的芳基酮也是特有的支架,其中Ph ∗(C 6 Me 5)酮是最佳选择。进一步的研究表明,该基序对于与2°醇形成β支链产物的烷基化至关重要,这也为研究非对映选择性和分子内氢借入过程提供了机会。

    well-characterized BVMOs including cyclohexanone, phenylacetone and 4-hydroxyacetophenone monooxygenase. Building on the Grogan classification/clustering of BVMOs, we have designated this new group of BVMOs, Group VI. Group VI BVMOs show an early divergence from the cyclopentanone monooxygenase (CPMO) type BVMOs (Group I). Substrate profiling using cyclic, bicyclic, aliphatic and aryl ketones show a clear divergence
    Baeyer-Villiger单加氧酶(BVMO)催化将酮化学,区域和对映选择性氧化为酯和内酯。迄今为止,尽管已经经常证明使用真菌进行的拜耳-维利格氧化作用,但是大多数可用的克隆BVMOs都来自细菌。在这里,我们报告从真菌黄曲霉的四个BVMOs的克隆和表征NRRL3357。系统发育分析表明,这四个BVMO与其他特征明​​确的BVMO包括一个明显的组聚在一起,包括环己酮,苯丙酮和4-羟基苯乙酮单加氧酶。在BVMO的Grogan分类/聚类的基础上,我们将BVMO的这一新组指定为VI组。VI组BVMO显示出与环戊酮单加氧酶(CPMO)型BVMO(I组)的早期差异。使用环状,双环,脂肪族和芳基酮进行的底物分析显示,不仅在这组新的BVMO与CPMO型BVMO之间,而且在四个黄曲霉之间,在功能和特异性上也存在明显的差异。BVMO旁系同源物,尽管它们具有很高的序列相似性。这项研究不仅有助于增加可用BVM
  • Dioxiranes. 20. Preparation and properties of some new dioxiranes
    作者:Robert W. Murray、Megh Singh、Ramasubbu Jeyaraman
    DOI:10.1021/ja00030a032
    日期:1992.2
    The in situ method for producing dioxiranes has been modified to permit the isolation in ketone solution of some nonvolatile dioxiranes. The dioxiranes have been characterized spectroscopically and, in some cases, by chemical reactions

  • Efficient Synthesis of ω-Functionalized Nonanoic Acids
    作者:L. Cotarca、P. Delogu、P. Maggioni、A. Nardelli、R. Bianchini、S. Sguassero

    Starting from cyclohexanone and acrylonitrile, a four-step synthesis of the title open-chain C9 compounds is reported. An improved protocol for cyanoethylation of cyclohexanone in the presence of a catalytic amount of cyclohexylamine afforded 3-(2-oxocyclohexyl)-propanenitrile (1) in 92% yield. Cyclohexaneperoxycarboxylic acid (CHPCA) is introduced as a highly efficient reagent in the Baeyer-Villiger rearrangement of 1, yielding over 90% of 2. Pyrolysis of 2 afforded under optimized conditions 3 in 92% yield and 99% regioisomeric purity, otherwise a mixture of three unsaturated isomeric ω-cyano nonenoic acids 3, 10 and 11 is obtained. Partial hydrogenation of 3 allowed the isolation of 4 in 90% yield. Hydrogenation of 4 at elevated hydrogen pressure gave 9-aminononanoic acid (5), whereas hydrolysis of 4 led to 1,9-nonanedioic acid (azelaic acid, 6). Both, 5 and 6 are valuable C9 monomers for the preparation of polyamides with specific properties.
    从环己酮和丙烯腈出发,报道了一种四步合成标题开链C9化合物的改进方法。在催化量的环己胺存在下,对环己酮的腈乙基化反应进行了改进,以92%的产率得到3-(2-氧代环己基)-丙腈(1)。环己烷过氧羧酸(CHPCA)作为一种高效试剂被引入到1的Baeyer-Villiger重排反应中,产率超过90%。2在优化条件下进行热解,得到92%产率和99%区域异构纯度的3,否则会得到三种不饱和异构的Φ-氰基壬烯酸3、10和11的混合物。3的部分氢化反应允许分离出4,产率为90%。在较高的氢压下对4进行氢化反应得到9-氨基壬酸(5),而4的水解反应则生成1,9-壬二酸(壬二酸,6)。5和6都是制备具有特定性能聚酰胺的有价值C9单体。
  • Hydrogen Borrowing Catalysis with Secondary Alcohols: A New Route for the Generation of β-Branched Carbonyl Compounds
    作者:Wasim M. Akhtar、Choon Boon Cheong、James R. Frost、Kirsten E. Christensen、Neil G. Stevenson、Timothy J. Donohoe

    hydrogen borrowing reaction employing secondary alcohols and Ph* (Me5C6) ketones to give β-branched carbonyl products is described (21 examples). This new C-C bond forming process requires low loadings of [Cp*IrCl2]2, relatively low temperatures, and up to 2.0 equiv of the secondary alcohol. Substrate-induced diastereoselectivity was observed, and this represents the first example of a diastereoselective
    描述了使用仲醇和 Ph* (Me5C6) 酮产生 β-支化羰基产物的借氢反应(21 个实施例)。这种新的 CC 键形成过程需要低负载量的 [Cp*IrCl2]2、相对较低的温度和高达 2.0 当量的仲醇。观察到底物诱导的非对映选择性,这代表了非对映选择性烯醇化物借氢烷基化的第一个例子。通过利用 Ph* 基团,β-支化产物可以使用逆弗里德尔-克拉夫茨反应直接裂解为相应的酯或酰胺。最后, 该协议应用于合成香料化合物 (±)-3-甲基-5-苯基戊醇。
