Triacetoxyperiodinane → HCID 18185015, 화합물

The above 5-trifluoromethyl-indan-2-yl-methanol (216 mg, 1 mmol) was dissolved in methylene chloride (15 mL) and the solution was cooled in an ice bath. To this solution was added Dess-Martin reagent (450 mg, 1.06 mmol) in four portions. The mixture was warmed to room temperature and stirred for 1 hr. The mixture was evaporated to dryness and the residue was triturated with petroleum ether (14 mL) and ether (7 mL). The precipitate was filtered out and the filtrate was extracted with ether and sodium bicarbonate solution. The organic layer was dried over sodium sulfate and solvents were evaporated to give 5-trifluoromethyl-indan-2-carbaldehyde (210 mg) as pale green oil. 1H-NMR (CDCl3) □ 9.78 (s, 1H), 7.48 (s, 1H), 7.43 (d, 1H), 7.32 (d, 1H), 3.33-3.38 (m, 3H), 3.15-3.27 (m, 2H).
