YieldReaction ConditionsOperation in experiment
With pyridinium chlorochromate; In dichloromethane; at 20℃; for 24h; [l-(Trifluoromethyl)cyclopropyl]methanol (1 g, 7.138 mmol) was stirred in dry dichloromethane (30 mL) and cooled to 0 C in an ice bath. Chloro-hydroxy-dioxo-chromium;pyridine (2.77 g, 12.85 mmol) was added in one portion, and the ice bath was removed and the reaction was stirred for 24 hours at room temperature. The reaction mixture was poured into 100 mL diethyl ether and filtered through a pad of silica with a layer of celite on top, eluting with diethyl ether. The resulting filtrate was dried over sodium sulfate, then filtered through cotton and used in the next step without concentration due to the volatility of the aldehyde. The crude filtrate was cooled to 0 C, and bromo(vinyl)magnesium (14.5 mL of 1 M, 14.50 mmol) (in THF) was slowly added. The reaction mixture was allowed to slowly warm to near room temperature over 2 hours. The reaction mixture was then cooled to 0 C, quenched with 1M HC1, and diluted with water. The layers were separated, and the aqueous was extracted 4 additional times with diethyl ether. The combined organics were washed with brine, dried over sodium sulfate and partially concentrated. The resulting crude material was used in the next step without further purification. 1-[1-(trifluoromethyl)cyclopropyl]prop-2-en-l-ol (approximately 1.25g crude, with substantial THF remaining) Crude *H NMR (400 MHz, DMSO) δ 5.95 - 5.84 (m, 1H), 5.36 (d, J = 5.2 Hz, 1H), 5.32 (ddd, J = 17.1, 2.1, 1.4 Hz, 1H), 5.18 (ddd, J = 10.4, 2.0, 1.3 Hz, 1H), 4.17 (tt, J = 6.4, 1.4 Hz, 1H), 0.95 - 0.87 (m, 4H).
