실험 절차

To a solution of trans-1-azido-4-(tert-butoxycarbonylamino)-2-cyclohexene (1.14 g, 4.79 mmol) in THF (50 mL) and water (5 mL) was added triphenylphosphine (2.60 g, 10 mmol) and the mixture was stirred at room temperature for 20 hours. The mixture was concentrated and the thus obtained material was purified by column chromatography on silica gel (10:1:1 CH2Cl2—CH3OH—NH4OH) followed by radial chromatography on silica gel (2 mm plate, 100:1:1 CH2Cl2—CH3OH—NH4OH) and provided 0.32 g (31%) of trans-1-amino-4-(tert-butoxycarbonylamino)-2-cyclohexene as a colorless oil. 1H NMR (CDCl3) δ 1.44 (s, 9H), 1.50-1.92 (m, 2H), 1.99-2.10 (m, 2H), 3.32 (br s, 1H), 4.10-4.19 (m, 1H), 4.47-4.60 (m, 1H), 5.57-5.77 (m, 2H);
