    Exploration of the Molecular Origin of the Azinomycin Epoxide: Timing of the Biosynthesis Revealed
    摘要:
    Streptomyces sahachiroi whole cell feeding experiments, utilizing putative precursors labeled with stable isotopes, established that the epoxide unit of the DNA cross-linked agents, azinomycin A and B, proceeds via a valine-dependent pathway and that hydroxylation and dehydration precedes formation of the terminal epoxide. Sodium 3-methyl-2-oxobutenoate, formed through a transimination reaction, was shown to be the penultimate precursor incorporated into the azinomycin epoxide.

  • Leveraging the n→π* Interaction in Alkene Isomerization by Selective Energy Transfer Catalysis
    作者:Tomáš Neveselý、John J. Molloy、Calum McLaughlin、Linda Brüss、Constantin G. Daniliuc、Ryan Gilmour
    DOI:10.1002/anie.202113600
    日期:2022.1.10
    Fumarate to maleate (EZ) isomerization was investigated to validate nO→ πC=O* interactions as a driving force for contra-thermodynamic isomerization. A general protocol based on selective energy transfer catalysis was developed with inexpensive thioxanthone as a sensitizer for the conversion of diverse fumarate derivatives, including tetrasubstituted alkenes. The involvement of nO→πC=O* interactions
    研究了富马酸到马来酸 ( E → Z ) 异构化,以验证 n O → π C=O * 相互作用作为反热力学异构化的驱动力。采用廉价的噻吨酮作为敏化剂,开发了基于选择性能量转移催化的通用方案,用于转化各种富马酸酯衍生物,包括四取代烯烃。 X 射线晶体学证实了 n O →π C=O * 相互作用的参与。
  • Steric Effects on the Stereochemistry of Old Yellow Enzyme-Mediated Reductions of Unsaturated Diesters: Flipping of the Substrate within the Enzyme Active Site Induced by Structural Modifications

    日期:2012.10.8
    The ene-reductase-mediated reduction of the carbon-carbon double bond of some alkyl 2-substituted butenedioates was investigated. The stereochemical outcome of the reaction was found to be influenced by steric effects. Ethyl and butyl citraconates were converted into the corresponding alkyl (R)-2-methylsuccinates with excellent enantioselectivity, whereas ethyl and butyl mesaconates were completely
    研究了一些烷基2-取代的丁烯酸酯的烯-还原酶介导的碳-碳双键的还原。发现该反应的立体化学结果受空间效应的影响。柠檬酸乙酯和柠檬酸叔丁酯以对映体选择性优良的形式转化为相应的烷基(R)-2-甲基琥珀酸烷基酯,而角鲨烷酯的乙基和丁基则完全没有反应性。将2-取代的富马酸甲酯还原为对映体富集的(S)-2-取代的琥珀酸甲酯,而(Z)-立体异构体则不被烯还原酶反应。进行标记实验以研究这些生物还原的机理并解释其立体化学结果。
  • Facile esterification of carboxylic acids with organophosphorus reagents

    日期:1983.1
    A mixture of alkyl phosphate esters (APE) obtained from P4O10 and alkanols taken in 1:6 mole ratio is an excellent esterification reagent for several classes of carboxylic acids. This new reagent offers several advantages compared to conventional reagents.
    由P 4 O 10获得的烷基磷酸酯(APE)和以1:6摩尔比获得的链烷醇的混合物是用于几类羧酸的优良酯化试剂。与常规试剂相比,这种新试剂具有多个优点。
  • Regioselective hydrolysis of diesters of (Z)- and (E)-2-methyl-butenedioic acids by PLE
    作者:Rudolf Schmid、Vassilia Partali、Thorleif Anthonsen、Henrik W Anthonsen、Lise Kvittingen
    DOI:10.1016/s0040-4039(01)01834-2
    日期:2001.11
    (Z)- and (E)-2-methyl-butenedioic acids (citraconic and mesaconic acid) were hydrolysed by pig live esterase, PLE. For the diethyl esters the enzyme showed low regioselectivity for both the (Z)- and the (E)-isomers. However, the hydrolysis of dimethyl and dipropyl (Z)-2-methyl-butenedioic acid gave a ratio of the monoesters of 95:5 and 85:15.
    (Z)-和(E)-2-甲基-丁烯二酸(柠康酸和中康酸)的二甲酯,二乙酯和二丙酯被猪活酯酶PLE水解。对于二乙酯,该酶对(Z)-和(E)-异构体均显示低的区域选择性。然而,二甲基和二丙基(Z)-2-甲基丁烯二酸的水解给出单酯的比例为95:5和85:15。
