  • Quinoline 2 carboxylic acids used in metal extraction processes
    申请人:Imperial Chemical Industries Limited
    公开号:US03941793A1
    公开(公告)日:1976-03-02
    Quinoline-2-carboxylic acids having in the 4-position a halogen atom or an optionally substituted hydrocarbyl group attached through an oxygen atom, optionally substituted by a hydrocarbyl group in the 3 position and optionally substituted in any of the 5, 6, 7 and 8 positions by halogen atoms, nitro or cyano groups, or optionally substituted hydrocarbyl groups each attained directly or through an oxygen atom, and containing in the substituents in the 3, 4, 5, 6, 7 and 8 positions a total of at least 3 carbon atoms form complexes with metals, especially copper. These complexes may be extracted by organic solvents from aqueous solutions of metal salts treated with the quinoline-2-carboxylic acids. The quinoline-2-carboxylic acids may be prepared from the corresponding 4-hydroxy compounds by (a) treating with a phosphorus halide, if necessary reacting the product with the alkali metal derivative of an alcohol or phenol and hydrolysing the ester group or (b) treating with a hydrocarbyl halide in presence of a base.
    在4位有一个卤素原子或可选择通过氧原子连接的一个可选择取代的烃基团的喹啉-2-羧酸,3位可选择取代的烃基团,5、6、7和8位中的任一位置可选择通过卤素原子、硝基或氰基或可选择取代的烃基团直接或通过氧原子取得,并且在3、4、5、6、7和8位的取代基中含有至少3个碳原子的金属络合物,特别是铜。这些络合物可以通过有机溶剂从经过喹啉-2-羧酸处理的金属盐水溶液中提取。喹啉-2-羧酸可以通过以下方法从相应的4-羟基化合物制备:(a)与磷卤素处理,必要时将产物与醇或酚的碱金属衍生物反应并水解酯基团,或(b)在碱存在的情况下与烃卤素处理。

    substituents attached to position 3 on the aminoalkylation was also investigated. Thus, reactions of 3-carbamoyl-substituted precursors with tertiary amine containing side-chains were also tested to afford new KYNA derivatives with two potential cationic centers. By means of NMR spectroscopic measurements, supported by DFT calculations, the dominant tautomer form of KYNA derivatives was also determined.
    犬尿烯酸 (KYNA) 作为富电子芳香体系在改良曼尼希反应中的应用已得到研究。通过使用存在于许多生物活性产物中的胺,如吗啉、哌啶或 N-甲基哌嗪和反应性明显不同的醛,如甲醛和苯甲醛,测试了反应的扩展可能性。还研究了连接到 3 位的取代基对氨基烷基化的影响。因此,还测试了 3-氨基甲酰基取代的前体与含有侧链的叔胺的反应,以提供具有两个潜在阳离子中心的新 KYNA 衍生物。通过由 DFT 计算支持的 NMR 光谱测量,还确定了 KYNA 衍生物的主要互变异构体形式。
