2-Phenylquinoline Chemical Properties,Usage,Production

Description

2-Phenylquinoline is the major quinoline alkaloid of Galipea iongiflora, a Bolivian plant used as treatment for cutaneous leishmaniasis. Antinociceptive properties of 2-phenylquinoline isolated from the bark of Galipea iongiflora against different models of pain in mice were evaluated.

Chemical Properties

white to light yellow crystalline powder

Uses

2-Phenylquinoline was used in quantitative structure-activity relationship (QSAR) analyses of estrogen receptor β-selective ligands.

Preparation

Synthesis of 2-phenylquinoline: Quinoline (1.0 g, 7.742 mmol) and phenyl lithium (2.30 mL, 2 M, 23.22 mmol) were reacted according to general procedure. Purification of the residue by silica gel column chromatography (EtOAc:MeOH:Et3N; 10-30:1:1 or PhMe:MeOH:Et3N; 10:1:1) gave 2-phenylquinoline (0.66 g, 42%) as an orange solid.
Aniline (0.140 g, 1.50 mmol) and cinnamaldehyde (0.132 g, 1.00 mmol) were dissolved in toluene in a reaction vial equipped with a magnetic stirrer bar, followed by the addition of K10 (0.50 g). The reaction mixture was heated at a temperature of 110 ?C for 3 hours. After completion of the reaction, the crude product was purified by column chromatography over silica gel eluting with a mixture of Hexane : Ethyl acetate (20:1) to produce 2-Phenylquinoline as a yellow solid (0.044 g, 21%); (m.p. 82-84 ?C) (lit. 84-85 °C); Rf 0.67 (20:1 hexane:ethyl acetate);
1H NMR (400 MHz, CDCl3) δH 7.46-7.51 (1H, m, H-4’), 7.53-7.56 (3H, m, H-6, 3’, 5’), 7.73- 7.77 (1H, m, H-7), 7.85 (1H, d, J = 8.31 Hz, H-5), 7.88-7.91 (1H, d, J = 8.31 Hz, H-3), 8.18- 8.27 (4H, m, H-4, 8, 2’, 6’)
