실험 절차

To a stirred solution of 2 (1.98 mmol, 360 mg) in acetone (7.76 mL) was added 10% aqueous hydrochloric acid solution (3.02 mL), and the resulting mixture was stirred at room temperature for 2.5 hours. The reaction mixture was then diluted with brine (40 mL) and extracted with methylene chloride/ethyl ether (1:2, 3×30 mL). The organic layers were combined and washed with saturated aqueous sodium bicarbonate solution (2×30 mL) and brine (1×30 mL), then dried over magnesium sulfate, filtered, and concentrated in vacuo to give 19 (251.6 mg, 1.92 mmol, 94%) as a yellow oil that was used in the next reaction without further purification: 1H NMR (CDCl3) δ 5.89 (1H, dd, J=0.5, 17.3 Hz), 5.15 (1H, dd, J=1, 3.5 Hz), 5.12 (1H, dd, J=0.5, 10 Hz), 2.42-2.28 (4H, m), 1.97-1.91 (2H, m), 1.74-1.68 (2H, m), 1.12 (3H, s); 13C NMR (CDCl3) δ 212.4, 145.5, 112.9, 38.2, 37.1, 27.4; MS (EI) m/z 138.1 [M+], 123.1, 110.1, 105.1, 97.1, 86.0 (100%), 68.1, 63.0, 54.9; HRMS (EI) calcd for C9H14O 138.1045 found 138.1048.
