  • TPAP-Catalyzed Direct Oxidation of Primary Alcohols to Carboxylic Acids through Stabilized Aldehyde Hydrates
    作者:Andrea-Katharina C. Schmidt、Christian B. W. Stark
    DOI:10.1021/ol2014335
    日期:2011.8.19
    We present a simple, mild, and highly effective method for the direct conversion of primary alcohols to carboxylic acids. TPAP serves as the catalyst, and NMO·H2O plays a dual role, acting as the co-oxidant and as a reagent for aldehyde hydrate stabilization. This previously unknown stabilizing effect of geminal diols by N-oxides is the key for the efficiency of the overall transformation.
    我们提出了一种简单,温和且高效的方法,用于将伯醇直接转化为羧酸。TPAP充当催化剂,NMO·H 2 O扮演双重角色,充当助氧化剂和醛水合物稳定剂。N氧化物对双生二醇的这种先前未知的稳定作用是整体转化效率的关键。

  • Flow <sup>1</sup>H nmr study of the rapid nucleophilic addition of amino acids to 4-formylpyridine
    作者:Liang K. Tan、Michael Cocivera
    DOI:10.1139/v82-113
    日期:1982.3.15

    Rapid addition of primary amino acids and imidazole to 4-formylpyridine to form carbinolamine intermediates in water has been studied by means of stopped-flow 1H nuclear magnetic resonance spectroscopy. The equilibrium constant Kn for this process was determined using stopped-flow uv spectroscopy. For the amino acid D,L-alanine and its derivatives, D,L-alanine methyl ester and D,L-alanylglycine, Kn does not appear to correlate with Ka, the acid dissociation constant. Values of kn, the addition rate constant, appear to be independent of pH and buffer concentration for these nucleophiles. The limited data indicate that the variation in rates of nucleophilic addition to 4-formylpyridine cannot be accounted for in terms of pKa, Kn or related to systematic changes in structure of the nucleophile. As a group, the primary amino acid D,L-alanine and its derivatives have comparable kn values within a factor of two in spite of their different pKa values. Imidazole, an aromatic secondary diamine, has a kn value that is 10 to 20 times larger than these primary amines and has a relatively small Kn value. At the same time, its kn value is comparable to that found previously for sarcosine, a secondary acyclic amino acid having substantially larger pKa and Kn values. The nucleophilic addition step of the primary amino acid and derivatives is rapid relative to the subsequent dehydration and prototropic shift steps. It occurs in a pH range at which pyridine nitrogen protonation is negligible.

    使用停流1H核磁共振光谱技术,研究了在水中将主要氨基酸和咪唑加入4-甲酰吡啶形成羟甲基胺中间体的快速反应。使用停流紫外光谱确定了该过程的平衡常数Kn。对于氨基酸D,L-丙氨酸及其衍生物D,L-丙氨酸甲酯和D,L-丙氨酰甘氨酸,Kn似乎与酸解离常数Ka无关。这些亲核试剂的加成速率常数kn的值似乎与pH和缓冲液浓度无关。有限的数据表明,亲核加成速率的变化不能用pKa,Kn或核试剂结构的系统变化来解释。作为一个组,主要氨基酸D,L-丙氨酸及其衍生物在kn值上相当,尽管它们的pKa值不同,但kn值相差不超过两倍。芳香性二元胺咪唑的kn值比这些主要胺大10到20倍,而Kn值相对较小。同时,它的kn值与之前发现的肌氨酸相当,后者是一种具有大大较大的pKa和Kn值的二级无环氨基酸。与随后的脱水和质子转移步骤相比,主要氨基酸和衍生物的亲核加成步骤是快速的。它发生在吡啶氮质子化可以忽略不计的pH范围内。
  • Hydration of Aza-aromatic Aldehydes. II. Solvent Effect on the Equilibrium Constants of the Hydration

    The equilibrium constants for the hydration reaction of 4-pyridinecarbaldehyde were determined in several solvents by 1H-NMR spectroscopic measurements. The hydration reactions were sensitive to the nature of the solvents. In strong donor solvents such as hexamethylphosphoric triamide, pyridine, and dimethyl sulfoxide, formation of the hydrate is far more favorable than in water or other poor donor
