| | 3-Quinolinecarboxaldehyde Usage And Synthesis |
| Chemical Properties | White to yellow powder | | Uses | 3-Quinolinecarboxaldehyde was used in the synthesis of 1,4-addition products. | | General Description | The structure and vibrational spectra of 3-quinolinecarboxaldehyde has been studied. | | Synthesis | General method: n-Butyllithium (2.5 M in hexane, 300 μL, 0.72 mmol) was added slowly and dropwise to an anhydrous THF (1.5 mL) solution of 3-bromoquinoline (100 mg, 0.48 mmol) at -78 °C. The reaction solution turned red. The reaction solution then turned red, followed by the addition of N,N-dimethylformamide (192 μL, 2.49 mmol). After maintaining the reaction temperature at -78 °C for 10 min, the reaction was quenched with deionized water. The reaction mixture was transferred to saturated aqueous sodium bicarbonate solution (10 mL) and extracted with ethyl acetate (3 × 10 mL). The organic phases were combined, dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (eluent: n-hexane solution of 10% ethyl acetate) to give quinoline-3-carbaldehyde as a yellow solid in 53% yield. | | References | [1] Tetrahedron Letters, 2003, vol. 44, # 10, p. 2033 - 2035 [2] Tetrahedron, 2003, vol. 59, # 43, p. 8629 - 8640 [3] Tetrahedron, 2002, vol. 58, # 17, p. 3387 - 3400 [4] European Journal of Medicinal Chemistry, 2019, p. 290 - 320 |
