실험 절차

Into a two-necked flask were placed 4-tert-butylcyclohexanone (74.1 mg, 0.480 mmol), and toluene (5.0 ml) as a solvent, and the mixture was subjected to heating under reflux conditions under an argon atmosphere. After the start of the refluxing, allyltrimethylsilane (82.3 mg, 0.720 mmol) was added, and a solution (0.1 M) of triflic imide (1.35 mg, 4.80 μmol) in toluene was added dropwise. After 5 min, triethylamine (0.486 mg, 4.80 μmol) was added, and the mixture was reacted for 10 min. Thereafter, cooled aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with hexane and dried over sodium sulfate. The solvent was evaporated under reduced pressure and purified by column chromatography to give the object product 4-tert-butyl-1-trimethylsilyloxy-1-cyclohexene (yield 88%).
