4265-16-1, Benzo[b]furan-2-carboxaldehyde is a benzofuran compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,4265-16-1
To a stirred solution of compound 2 (2.27 g, 14.30 mmol) in methanol (20 mL) at 0 C sodium borohydride (0.65 g, 17.16 mmol) was added in three portions over a period of 15 minutes, and then at room temperature for 2 h. TLC was used to monitor the reaction progress. A small amount of dilute HCl (1N) was added and the mixture was stirred for 20 min. The solvent was evaporated under vacuum and the residue was purified on silica gel column (petroleum ether:EtOAc = 5:1) to give product 3 (2.03 g, 96%) as white powder. 1H NMR (400 MHz, CDCl3): delta 7.45-7.35 (2H, m, H-4,7), 7.20-7.10 (2H, m, H-5,6), 6.46 (1H, s, H-3), 4.60 (2H,s, CH2), 4.34 (1H, br. s, OH). 13C NMR (100 MHz, CDCl3): delta 156.83 (C-7a), 155.32 (C-2), 128.34 (C-3a), 124.32 (C-6), 122.84 (C-5), 121.18 (C-4), 111.27 (C-7), 104.07 (C-3), 57.66 (CH2).
4265-16-1 Benzo[b]furan-2-carboxaldehyde 61341, abenzofuran compound, is more and more widely used in various fields.
