实验步骤: To a solution of 1,2,5-thiadiazepane 1,1-dioxide (0.10 g, 0.67 mmol) in methylene chloride (2 mL) at −10 C was added methane sulfonyl chloride (0.06 mL, 0.77 mmol) and triethylamine (0.108 mL, 0.77 mmol). After 72 hr the reaction was quenched with NaHCO3 (sat. aq.) and extracted into methylene chloride. The organic extracts were dried (MgSO4) and the solvent evaporated in vacuo. The residue was purified by chromatography (SiO2, EtOAc/CH2Cl2: 1:1) to afford the title compound as a white solid. After 72 hr the reaction was quenched with NaHCO3 (sat. aq.) extracted into methylene chloride The organic extracts were dried (MgSO4) the solvent evaporated in vacuo The residue was purified by chromatography (SiO2, EtOAc/CH2Cl2: 1:1)

实验步骤: A solution of 2-[(vinylsulfonyl)amino]ethanaminium chloride (1.17 g, 6.24 mmol) in methanol (50 ml) at room temperature, was treated with triethylamine (0.87 mL, 6.24 mmol) and then stirred for 28 hr. Silica gel (10 g) was added to the solution. The solvent was evaporated in vacuo and the remaining silica gel was applied to a column of silica gel and chromatographed eluting with 4% ammonium hydroxide in acetonitrile to afford the title compound as an oil. Silica gel (10 g) was added to the solution The solvent was evaporated in vacuo chromatographed eluting with 4% ammonium hydroxide in acetonitrile
