实验步骤: 1-(10-Aza-tricyclo[6.3.1.02,7]dodeca-2(7),3,5-trien-10-yl)-2,2,2-trifluoro-ethanone (530 mg, 2.1 mmol) was added to chlorosulfonic acid (2 mL, 30 mmol) and stirred for 5 minutes. The mixture was quenched with ice, extracted with ethyl acetate, dried (Na2SO4), filtered and concentrated to provide an oil (640 mg, 87%). (TLC 30% ethyl acetate/hexanes Rf 0.15). The mixture was quenched with ice extracted with ethyl acetate dried (Na2SO4) filtered concentrated

The resulting yellow mixture was stirred for 30 minutes then poured over ice and saturated aqueous NaHCO3 solution. After stirring 20 minutes the mixture was extracted with CH2Cl2 (3×30 mL). The organic layer was dried through a cotton plug then concentrated to a orange-yellow oil (255 mg, 86%).

实验步骤: (Based on the method described by Coon, C. L.; Blucher, W. G.; Hill, M. E. J. Org. Chem. 1973, 25, 4243.) To a solution of trifluoromethanesulfonic acid (2.4 ml, 13.7 mmol) in CH2Cl2 (10 ml) stirred at 0° C. was slowly added nitric acid (0.58 ml, 27.4 mmol) generating a white precipitate. After 10 minutes the resulting mixture was cooled to −78° C. and treated with 1-(10-aza-tricyclo[6.3.1.02,7]dodeca-2(7),3,5-trien-10-yl)-2,2,2-trifluoro-ethanone (3.5 g, 13.7 mmol) in CH2Cl2 (15 ml) dropwise from an addition funnel over 5 minutes. The reaction was stirred at −78° C. for 30 minutes then warmed to 0° C. for 1 hour. The reaction mixture was poured into a vigorously stirred ice (100 g). The layers were separated and the aqueous layer extracted with CH2Cl2 (3×30 ml). The organic layer was combined and washed with H2O (3×30 ml). The combined organic layer was washed with saturated aqueous NaHCO3 solution (20 mL) and H2O (20 mL) then dried through a cotton plug and concentrated to give an orange oil that solidified on standing (4.2 g).
