    N-烷基化聚(对苯甲酰胺)的螺旋结构
    摘要:
    通过链增长缩聚方法合成在氮原子上带有手性侧链的聚(对苯甲酰胺)1。聚酰胺表现出明确的分子量和窄的多分散性。聚酰胺在几种有机溶剂 (CH(3)CN、CHCl(3) 和 CH(3)OH) 中的溶液显示出耦合振荡器的分散型 CD 信号特征,并且与相应的单体相比要大得多。就检测而言,CD 信号取决于聚酰胺的温度和分子量,但与溶剂无关。吸收和 CD 光谱的激子模型分析为这些聚酰胺在溶液中的二级结构提供了清晰的图片,即 N-烷基化聚(对苯甲酰胺)具有右手螺旋构象((P)-螺旋)。在固态下,

    摘要:
    已经获得了在50°C下于H(2)O中水解2-氨基苯甲酸的三氟乙基,苯基和对硝基苯基酯的速率常数。拟一级反应速率常数k(obsd)与pH无关,与pH 8至pH 4(胺基共轭酸的pK(a))无关。2-氨基苯甲酸酯在不依赖pH的反应中以相似的速率常数水解,在D(2)O中,这些水反应比H(2)O中的反应慢约2倍。最可能的机制涉及相邻胺基团在分子内的一般碱催化作用。与相应的对位取代的酯或苯甲酸酯的不依赖pH的水解相比,不依赖pH的反应的速率提高了50-100倍。与氢氧根离子催化的反应相比,用苯酯在pH 4下k(obsd)的增强是10(5)倍。就其在酶催化中的相对优点和缺点,评估了分子内一般碱催化的反应。一般的碱催化反应在低pH条件下比对pH和离去基团有明显依赖性的亲核反应更快。

  • Substituent Effects on the Base-Catalysed Hydrolysis of Phenyl Esters of para-Substituted Benzoic Acids
    作者:Ingrid Bauerová、Miroslav Ludwig
    DOI:10.1135/cccc20001777
    日期:——

    Seventeen model phenyl esters of 4-substituted benzoic acids were synthesised by the reaction of substituted benzoyl chlorides with phenol in aqueous alkaline solutions (Schotten-Baumann reaction), in pyridine (Einhorn reaction), or by the reaction of substituted benzoic acids with phosphorus oxychloride. Structures and purity of the model compounds were confirmed by 1H NMR and 13C NMR spectroscopy as well as by HPLC and elemental analysis. Phenyl 4-aminobenzoate was synthesised by reduction of phenyl 4-nitrobenzoate in methanol on palladium. Kinetics of base-catalysed hydrolysis of model phenyl esters occurring by the BAc2 mechanism were measured by UV spectrophotometry in 50% (v/v) aqueous dimethyl sulfoxide solutions at 25 °C under pseudo-first-order conditions, (c[NaOH] = 0.001-1.0 mol l-1). The addition of OH- to phenyl benzoates was used to establish the kinetic J-E acidity scale. Linear relation between J-E and log kobs with the slope near unity was found for all the model compounds. The kinetic constants of hydrolysis of phenyl esters of 4-substituted benzoic acids precisely obey the Hammett relationship (σp) with ρ = 2.44. Quantitatively comparable results have been obtained by application of Alternative Interpretation of Substituent Effects theory (AISE) using the σi set of substituent constants.

    4-取代苯甲酸的17种模型苯酯通过取代苯甲酰氯性碱性溶液中(Schotten-Baumann反应),在吡啶中(Einhorn反应),或通过取代苯甲酸亚磷酸反应合成。模型化合物的结构和纯度通过1H NMR和13C NMR光谱以及HPLC和元素分析得到确认。苯基4-苯甲酸是通过在上在甲醇中还原苯基4-硝基苯甲酸合成的。在25°C下,通过伪一级条件(c[NaOH] = 0.001-1.0 mol l-1)在50%(体积比)二甲基亚砜溶液中,利用UV分光光度法测量了发生BAc2机制的模型苯酯的碱催化解动力学。将OH-加入苯基苯甲酸酯以建立动力学J-E酸度标度。对于所有模型化合物,发现了J-E与log kobs之间的线性关系,斜率接近于单位。4-取代苯甲酸酯的解动力学常数精确遵守Hammett关系(σp),ρ = 2.44。使用σi取代基常数集合,通过应用替代取代基效应理论(AISE),获得了定量可比较的结果。
  • Kinetic Study of Hydrolysis of Benzoates. Part XXV. Ortho Substituent Effect in Alkaline Hydrolysis of Phenyl Esters of Substituted Benzoic Acids in Water

    The second-order rate constants k2 for alkaline hydrolysis of phenyl esters of meta-, para- and ortho-substituted benzoic acids, X-C6H4CO2C6H5 (X = H, 3-Cl, 3-NO2, 3-CH3, 4-NO2, 4-Cl, 4-F, 4-CH3, 4-OCH3, 4-NH2, 2-NO2, 2-CN, 2-F, 2-Cl, 2-Br, 2-I, 2-CH3, 2-OCH3, 2-CF3, 2-NH2), and of substituted phenyl esters of benzoic acid, C6H5CO2C6H4-X (X = 2-I, 2-CF3, 2-C(CH3)3, 4-Cl, 4-CH3, 4-OCH3, 4-NH2), have been measured spectrophotometrically in water at 25 °C. The substituent effect in alkaline hydrolysis of phenyl esters of para-substituted benzoic acids, similar to that for ethyl esters of para-substituted benzoic acids, was found to be precisely described by the Hammett relationship (ρ = 1.7 in water). The log k value for alkaline hydrolysis of phenyl and ethyl esters of meta-, para- and ortho-substituted benzoic acids, X-C6H4CO2R, was nicely correlated with log km,p,ortho = log ko + (ρ)m,pσ + (ρI)orthoσI + (ρ°R)orthoσ°R + δorthoEsB where σ, σI, σ°R are the Hammett polar, Taft inductive and Taft resonance (σ°R = σ° - σI) substituent constants, respectively. EsB is the steric scale for ortho substituents calculated on the basis of the log k values for the acid hydrolysis of ortho- substituted phenyl benzoates in water owing to the ortho substituent in the phenyl of phenyl benzoates. In water, the main factors responsible for changes in the ortho substituent effect in alkaline hydrolysis of phenyl and ethyl esters of ortho-substituted benzoic acids, X-C6H4CO2R, were found to be the inductive and steric factors while the role of the resonance term was negligible ((ρ°R)ortho ca. 0.3). In alkaline hydrolysis of substituted benzoates in neat water, the ortho inductive effect appeared to be 1.5 times and steric influence 2.7 times higher than the corresponding influences from the ortho position in the phenyl of phenyl benzoates. The contributions of the steric effects in alkaline hydrolysis of esters of ortho-substituted benzoic acids was found to be approximately the same as in acid hydrolysis of esters of ortho-substituted benzoic and acid esterification of ortho-substituted benzoic acids.
