4-Quinolinecarboxaldehyde Chemical Properties,Uses,Production

Chemical Properties

yellow to yellow-brown crystalline powder

Occurrence

The common presence of 4-quinolinecarboxaldehyde in honey from Galicia (northwest of Spain). As opposed to other quinoline carboxylic acid derivatives, the 4- quinolinecarboxaldehyde species has not been correlated with the anti-diabetic properties of honey; nevertheless, it appears to be active against intestinal bacteria.

Uses

4-Quinolinecarboxaldehyde was used in the synthesis of lepidylamines. It also shows antimicrobial activity toward human intestinal bacteria such as Clostridium perfringens.

4-Quinolinecarboxaldehyde

4363-93-3

The general procedure for the synthesis of 4-quinolinecarboxaldehyde from 4-methylquinoline was as follows: 5.0 g (35 mmol) of 4-methylquinoline and 5.0 g (45 mmol) of selenium dioxide were dissolved in toluene under argon protection and heated to reflux for 24 hours. After completion of the reaction, the reaction mixture was diluted with dichloromethane, washed sequentially with saturated saline and dried with anhydrous magnesium sulfate. After concentration under reduced pressure, the reaction was purified by silica gel column chromatography using a solvent mixture of hexane and ethyl acetate (4:1, v/v) as eluent to give 4.0 g (73% yield) of the target product 4-quinolinecarboxaldehyde as a solid. Nuclear magnetic resonance hydrogen spectroscopy (1H NMR) data: δ 10.54 (s, 1H), 9.22 (d, J = 4.3 Hz, 1H), 9.04 (d, J = 8.6 Hz, 1H), 8.24 (d, J = 8.2 Hz, 1H), 7.84 (t, J = 7.6 Hz, 1H), 7.81 (d, J = 4.3 Hz, 1H), 7.76 (t , J = 8.0 Hz, 1H). Nuclear magnetic resonance carbon (13C NMR) data: δ 193.1, 150.7, 149.5, 137.0, 130.4, 130.3, 129.6, 126.0, 124.7, 124.1. mass spectrometry (electrospray ionization) data: m/z 158.0 (100%) ([M + H]+), 130.2.
