Description

2-联芳基-6-芳基喹啉及其制备方法2-biaryl-6-arylquinoline and its preparation method

技术领域technical field

本发明属于有机合成领域,具体涉及一类2-联芳基-6-芳基喹啉化合物,以及该类化合物的合成方法。The invention belongs to the field of organic synthesis, and in particular relates to a class of 2-biaryl-6-aryl quinoline compounds and a synthesis method of the compounds.

背景技术Background technique

喹啉衍生物具有生物活性和药理活性,广泛应用于医药、农药等工业生产。喹啉衍生物最早从煤焦油中提取,技术路线工艺复杂,其产品种类有限,一些重要的喹啉衍生物通过该方法不能获得。近年来,在传统合成路线基础上,发展了以过渡金属络合物为催化剂的新的合成路线,是目前研究最多和最有前途的一种方法。为提高反应的原子经济性和合成效率,一锅法多组分反应构建多个共价键的反应引起化学家们的广泛兴趣。在醇参与的反应中,研究较多的催化剂是Ru、Ir等金属络合物;其中RuCl2(DMSO)4(DMSO=二甲基亚砜)结构简单、易于合成、现已商品化,是用于催化此反应效率和催化效果较好的催化剂之一。Quinoline derivatives have biological activity and pharmacological activity, and are widely used in industrial production such as medicine and pesticide. Quinoline derivatives were first extracted from coal tar. The technical route is complex and the product types are limited. Some important quinoline derivatives cannot be obtained by this method. In recent years, on the basis of traditional synthetic routes, a new synthetic route using transition metal complexes as catalysts has been developed, which is currently the most studied and most promising method. In order to improve the atom economy and synthetic efficiency of the reaction, the one-pot multicomponent reaction to construct multiple covalent bonds has attracted widespread interest among chemists. In the reaction involving alcohol, metal complexes such as Ru and Ir are the most studied catalysts; among them, RuCl 2 (DMSO) 4 (DMSO=dimethyl sulfoxide) has a simple structure, is easy to synthesize, and is now commercialized. It is one of the catalysts with better efficiency and catalytic effect for catalyzing this reaction.

近年来,以芳基取代的喹啉衍生物为配体的金属有机化合物在材料化学等领域的广泛应用前景,引起人们的极大兴趣。而芳基取代的喹啉衍生物,特别是联芳基的喹啉衍生物还很少有报道。In recent years, metal-organic compounds with aryl-substituted quinoline derivatives as ligands have aroused great interest for their wide application prospects in materials chemistry and other fields. However, aryl-substituted quinoline derivatives, especially biaryl-substituted quinoline derivatives, are rarely reported.
