Abstract
The invention discloses a method for preparing quinoline derivatives by photocatalysis of N-aryl glycine ester, which comprises the following steps: dissolving the N-aryl glycine ester compound and the butynedicarboxylic acid ester compound in a dimethyl sulfoxide solvent, adding a photosensitizer and dicumyl peroxide, reacting at room temperature for 24 hours under the condition of blue light irradiation, and after the reaction is finished, performing column chromatography separation to obtain the quinoline derivative. The preparation method has the advantages of cheap and easily-obtained raw materials, mild reaction system, simple operation and high yield. Quinoline derivatives have a wide range of applications and are also useful as synthetic intermediates.
Description
Technical Field
The invention belongs to the field of organic synthetic chemistry, and relates to a method for preparing a quinoline derivative by photocatalysis of N-aryl glycine ester, in particular to a method for preparing a quinoline derivative by an addition cyclization reaction of an N-aryl glycine ester compound and a butyne dicarboxylic acid ester compound in the presence of an oxidant and a photosensitizer and under the irradiation of a blue light LED.
Background
Quinoline and its derivatives are nitrogen-containing heterocycles widely existing in nature, have wide biological activities, are important synthetic intermediates in the field of organic synthesis, and have wide application in other industrial fields, so the synthetic method thereof is concerned. The traditional quinoline skeleton synthesizing method includes Skraup reaction, combes reaction, conrad-Limbach reaction, doebner-VonMuller reaction, gould-Jacobs reaction, friedlander reaction, povavov reaction, pfitzinger reaction and the like, and the reaction conditions are harsh, side reactions are more, and pollution is serious. Recently, numerous documents report methods for preparing quinoline derivatives by photocatalytic reaction, such as: (1) Zhang et al reported a method (j.org.chem., 2016,81,12433-12442.) of producing quinoline derivatives by a visible light catalytic oxidative dehydrogenation coupling/aromatization tandem reaction of glycine ester and unactivated olefin, but the reaction requires a synergistic effect of copper salt and a photocatalyst to be able to react, and the reaction system is relatively complex. (2) Jiang et al also reported that a variety of alpha-branched 2-vinylpyridine and 2-vinylquinoline compounds were subjected to redox, radical conjugate addition, and protonation processes with glycine, respectively, using visible light-induced dual concerted catalysis of chiral phosphoric acid and DPZ photosensitizer, and finally a variety of chiral 3- (2-pyridine/quinoline) -3-substituted amine compounds were obtained in high yield (J.Am.Chem.Soc., 2018,140, 6083-6087.). In the reaction, the reaction can be carried out only by the synergistic action of the cobalt salt, the additive and the photocatalyst, the reaction system is complex, the separation is difficult, the substrate applicability is poor, and the large-scale popularization and application are difficult.
Therefore, there is still a need to develop and optimize new methods for preparing polysubstituted quinoline derivatives.
