Versuchsvorschrift
Futoenone (50 mg, 0.15 mmol) and 30% sulfuric acid (7.5 ml) are added to a 25 ml round bottom flask. This mixture is heated with a heating mantle to reflux for approximately six hours. The reaction mixture is diluted with distilled water and crystals begin to precipitate. The flask is placed in a refrigerator to aid in precipitation. The crystals are collected by filtration, 300 mg (80%). M+(CI)=327. 1H NMR ppm: 0.59 (3H, d), 1.25 (1H, s), 1.72 (1H, t), 2.03 (1H, m), 2.17 (1h, d), 2.35 (2H, m), 2.53 (1H, m), 5.06 (1H, t), 5.72 (1H, s), 5.83 (1H, s), 5.93 (2H, s), 6.69 (3H, m).
