Reaction Steps

4,4-difluoro-3-ethyl-3-trimethylsilyloxy-5-hexene (2.00 g, 8.88 mmol) was dissolved in dichloromethane (80 ml), and the solution was cooled to -78° C. A gaseous mixture of O3 in O2 was passed into the solution until it became blue. Nitrogen was bubbled through the solution to remove excess ozone, dimethyl sulfide (3 ml) was added, and the solution was brought slowly to room temperature. Following ozonide decomposition, dichloromethane was added, and the organic layer was washed with water (twice), dried over CaCl2 and concentrated under reduced pressure. Flash chromatography (50 g silica gel; 5% EtOAc in petroleum ether as eluant) to give the title compound as a pale yellow oil, δ 0.14 (s 9H), 0.91 (m, 6H), 1.64 (m, 2H), 1.85 (m, 2H), 9.55 (t, 1H).
