4-HYDROXY-1H-INDOLE-3-CARBALDEHYDE Chemical Properties,Usage,Production
Uses
4-Hydroxy-1H-indole-3-carbaldehyde is a plant metabolite. 4-Hydroxy-1H-indole-3-carbaldehyde can be isolated from Capparis spinosa L. 4-Hydroxy-1H-indole-3-carbaldehyde can be used in the synthesis of fluorescent probe. 4-Hydroxy-1H-indole-3-carbaldehyde can be used in the study of inflammation-related diseases[1][2][3].
Definition
ChEBI: 4-hydroxyindole-3-carbaldehyde is a heteroarenecarbaldehyde that is 4-hydroxyindole in which the hydrogen at position 3 has been replaced by a formyl group. It has a role as a plant metabolite. It is a member of hydroxyindoles and a heteroarenecarbaldehyde.
Synthesis
2380-94-1
68-12-2
81779-27-3
Example 1: Synthesis of 4-hydroxy-1H-indole-3-carbaldehyde 1. 7.35 mL of phosphorus oxychloride was slowly added dropwise to 15 mL of dry N,N-dimethylformamide under cooling conditions in an ice-methanol bath with stirring for 15 minutes. 2. 5.0 g of 4-hydroxyindole dissolved in 10 mL of anhydrous N,N-dimethylformamide was added slowly dropwise to the above mixture under cooling in an ice bath. 3. The reaction mixture was stirred at room temperature for 2 hours. 4. Under cooling in an ice bath, water was added to the reaction mixture and adjusted to alkaline with 30% aqueous sodium hydroxide solution and stirring was continued for 15 minutes. 5. The mixture was acidified to pH 4 with 5N hydrochloric acid and the precipitate was collected by filtration. 6. The precipitate was washed with water and dried to give 4.99 g of 4-hydroxy-1H-indole-3-carbaldehyde crude product in 82% yield. 7. The crude product was recrystallized with methanol to give yellow crystals. Product characterization. 1H-NMR (DMSO-d6) δ: 6.54 (1H, dd, J = 8.1, 0.9 Hz), 6.95 (1H, dd, J = 8.1, 0.9 Hz), 7.13 (1H, t, J = 8.1 Hz), 8.37 (1H, s), 9.64 (1H, s), 10.54 (1H, br s), 12.35 (1H, br s). br s). Melting point: 190-193 °C.
