実験手順

A solution of n-butyl lithium (1.8 ml) was added dropwise to a 5 ml THF solution of 560 mg of 1,1-(ethylenedioxy)-4-methyl-3-(phenylsulfonyl)-cyclohexane and 4 mg of triphenylmethane under an argon gas stream at −78° C. The resulting mixture was stirred for 10 minutes and then reacted at room temperature for one hour. HMPT (1 ml) was added and the resulting mixture was cooled to −78° C. again, followed by the dropwise addition of a 2 ml THF solution of 205 mg of 14-bromo-1-tetradecanol. After reaction at −20° C. for 2 hours, the reaction mixture was poured into a saturated solution of ammonium chloride. The resulting mixture was extracted with ether. The organic layer was washed with water and saturated saline, dried over magnesium sulfate and distilled under reduced pressure to remove the solvent. The residue was purified by chromatography on a silica gel column while using hexane-ethyl acetate, whereby 1,1-(ethylenedioxy)-3-(14-hydroxytetradecyl)-4-methyl-3-(phenylsulfonyl)-cyclohexane was obtained in the form of a colorless oil (yield: 98%).
