摘要

To a solution of ethyl N-hydroxycarbamate (1.05 g, 10 mmol) in acetone (30 mL) was added thallium ethoxide (2.49 g, 10 mmol) at 0 OC. The mixture was stirred at 0" C for 20 min, and the precipitated white solid was collected and dried to give the thallium salt (2.93 g, 95%). The crude material (1.33 g, 4.3" 01) was suspended in methylene chloride (50 mL), and trifluoromethanesulfonic anhydride (1.18 g, 4.4 mmol) was added at-30 to-40 OC with ...
