実験手順: Pyridine (11.7 mL, 145 mmol), 4-dimethylaminopyridine (DMAP, 0.59 g, 4.82 mmol) and tert-butyldimethylsilyl chloride (8.71 g, 57.8 mmol) were added to a solution of 1-allylcyclohexanol (48.2 mmol) in acetonitrile (120 mL). The reaction was heated at reflux overnight, then cooled to rt and concentrated to about 50 mL under reduced pressure. The solution was cooled to 0° C. and tert-butyldimethylsilyl triflate (13.3 mL, 57.8 mmol) was added. After the solution had stirred overnight at rt, additional tert-butyldimethylsilyl triflate (5.00 mL) was added and the solution was stirred for 6 h longer. The reaction was quenched with saturated aqueous sodium bicarbonate (120 mL) and extracted with dichloromethane (100 mL, then 2×75 mL). The combined organic layers were dried over MgSO4, filtered, and concentrated to give a colorless oil that was purified on a on a HORIZON High-Performance Flash Chromatography (HPFC) instrument (available from Biotage, Inc, Charlottesville, Va., USA) (silica gel, gradient elution with 0-5% ethyl acetate/hexanes) to afford [(1-allylcyclohexyl)oxy](tert-butyl)dimethylsilane as a colorless oil (11.96 g, 97%).

The cloudy white reaction mixture was allowed to stir at rt overnight. The reaction was quenched with saturated aqueous NH4Cl (100 mL) and diluted with water (20 mL) and diethyl ether (50 mL). The mixture was transferred to a separatory funnel and the layers were separated. The aqueous layer was extracted with diethyl ether (2×50 mL). The combined organic layers were washed with brine (100 mL), dried over MgSO4, filtered, and concentrated to afford a 1-allylcyclohexanol as a colorless oil (6.97, 103%) that contained a small amount of diethyl ether.
