실험 절차

To a solution of tert-butyl (1R,4S)-3-oxo-2-azabicyclo[2.2.1]hept-5-ene-2-carboxylate (500. mg, 2.39 mmol) in acetone (20.0 mL) was added a 4% aqueous solution of osmium tetroxide in H2O (0.015 mL, 0.00239 mmol). To the resulting mixture was added a 10.2 M aqueous solution of N-methylmorpholine N-oxide (0.262 mL, 2.67 mmol) dropwise over 1 h. At this point, a 0.240 M solution of aqueous sodium bisulfite (1.00 mL, 0.240 mmol) was added, the mixture was filtered through celite and concentrated in vacuo. The residue was purified via silica gel chromatography eluting with a gradient of 20 to 70% EtOAc in DCM to afford the title compound (420. mg, 72%). LC/MS: Rt=0.94 min, ES+ 244 (FA standard).
