实验步骤: 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%).

实验步骤: A solution of allyl magnesium bromide in diethyl ether (1 M, 53 mL, 53 mmol) was added dropwise to a solution of cyclohexanone (5.00 mL, 48.2 mmol) in diethyl ether at 0° C. 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.

实验步骤: A flame-dried 100 mL three-necked flask was purged with N2, and charged with Cu(OTf)2 (95 mg, 0.26 mmol), 1-allylcyclohexanol (960 mg, 9.86 mmol) and acetonitrile (HPLC grade). Solid [N-(p-Toluenesulfonyl)imino]phenyliodinane (PhINTs, prepared as described in Inorgania Chimica Acta 2003, 342, 301-304, 1.97 g, 5.28 mmol) was added in a single portion and the mixture was stirred at rt until all PhINTs had dissolved (within 5 to 30 min). The solvent was removed and the residue was chromatographied on silica gel eluted with hexane/EtOAc to give 1-((1-tosylaziridin-2-yl)methyl)cyclohexanol (217 mg, 13%). MS m/z 310 (M+H+).
