反応条件: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Ethyl N-mesitylsulfonyloxyacetimidate (20 g, 65.7 mmol, 1 eq) was dissolved in 1,4-dioxane (6 ml) and the solution was cooled to 0° C. To the mixture was added dropwise Perchloric acid (10 m), and the reaction mixture was then stirred at 0° C. for 45 minutes. The solution was poured into ice water, and the solid precipitated was filtered and washed with water and dried for 15 minutes in vacuum. The sample was stored in plastic container at −20° C. 1HNMR (400 MHz, DMSO-d6): δ 2.32 (s, 3H), 2.64 (s, 6H), 4.98 (br peak, 2H), 6.99 (s, 2H). the solid precipitated was filtered washed with water dried for 15 minutes in vacuum was stored in plastic container at −20° C

実験手順: 70% aq. perchloric acid (4.34 g, 2.6 ml, 43.2 mmol, Eq: 4.12) was added to ethyl N-mesitylsulfonyloxyacetimidate (2.99 g, 10.5 mmol, Eq: 1.00) in THF (4 ml) at 0° C. The reaction mixture was stirred for 1 h at 0° C. The mixture was poured into water (60 ml) and extracted with CH2Cl2 (20 ml+2×10 ml). The combined organic layers were dried over Na2SO4. The solution was used without further purification in the next step. extracted with CH2Cl2 (20 ml+2×10 ml) The combined organic layers were dried over Na2SO4 The solution was used without further purification in the next step
