    Do enzymes recognise remotely located stereocentres? Highly enantioselective Candida rugosa lipase-catalysed esterification of the 2- to 8-methyldecanoic acids
    摘要:
    Several racemic methyl decanoic acids have been synthesised and Successfully resolved in esterification with 1-hexadecanol at a(w)=0.8 in cyclohexane using immobilised Candida rugosa lipase (CRL) as the catalyst. The enantiomeric ratios (E=2.8-68) obtained were surprisingly high even when the methyl group was as remotely located as in 8-methyldecanoic acid (E=25). Interestingly, the lipase shows enantiopreference for the S-enantiomer when the methyl group is located on even numbered carbons i.e. for the 2-,4-,6- and 8-methyldecanoic acids and to the R-enantiomer when the methyl group is located on uneven numbered carbons i.e. for the 3-,5- and 7-methyldecanoic acids.

    厌氧烷烃通过富马酸酯加成降解的重排生物特征代谢产物的合成和质谱。
    摘要:
    厌氧烷烃生物降解过程中的代谢产物分析在揭示激活机制中起着重要作用。除了通过富马酸酯添加被认为是常见的生物标志物的琥珀酸烷基酯外,C骨架重排的下游代谢产物也可以被视为生物标志物。但是,很难在环境样品和富集培养物中检测到中间代谢物,导致缺乏直接的证据来证明富马酸酯添加途径的发生。在这项工作中,建立了重排代谢物的合成方法。合成了四种化合物,即丙二酸丙二酸,2-(2-甲基丁基)丙二酸,2-(2-甲基戊基)丙二酸和2-(2-甲基辛基)丙二酸,并通过四种衍生方法进行了测定。此外,获得了它们的质谱。在m / z 133 + 14n,160 + 28n,173 + 28n和[M-(45 + 14n)] +处观察到四个特征离子(对于乙基和正丁基酯,n = 0和2)。对于甲基酯化,质谱特征为m / z 132、145和[M-31] +,而对于甲硅烷基化,片段为m / z 73、147、217、248、261和[M-15]

    propylmalonic acid, 2-(2-methylbutyl)malonic acid, 2-(2-methylpentyl)malonic acid and 2-(2-methyloctyl)malonic acid, were synthesized and determined by four derivatization approaches. Besides, their mass spectra were obtained. Four characteristic ions were observed at m/z 133 + 14n, 160 + 28n, 173 + 28n and [M - (45 + 14n)]+ (n = 0 and 2 for ethyl and n-butyl esters, respectively). For methyl esterification
