实验步骤: To a solution of 5-(tert-butyl-dimethyl-silanyloxy)-pentanol (16.8 mmol, 3.66 g) in dichloromethane (30 mL) were added water (5.6 mL), potassium bromide (1.7 mmol, 202 mg), n-tetrabutylammonium hydrogensulfate (0.84 mmol, 290 mg), and TEMPO (30 mg) at room temperature. The resulting light brown solution was cooled to ˜5° C. and a solution of sodium hypochlorite (19.3 mmol, 30 mL, 5%) was added dropwise at this temperature. After addition of half of the sodium hypochlorite solution, solid potassium carbonate (300 mg) was added to maintain the reaction mixture basic. Then, the remaining sodium hypochlorite solution was added at 5-10° C. By this point, a precipitate had formed and the reaction mixture was stirred for another 1 h at ˜10-15° C. Then, water (100 mL) was added and the resulting solution was extracted into diethyl ether (2×100 mL). The combined organic extracts were washed with brine solution (150 mL) and the organic layer was dried over anhydrous magnesium sulfate. Filtration of the drying agent and the removal of the solvent gave 5-(tert-butyl-dimethyl-silanyloxy)-pentanal (3.32 g, 91%) as a light brown oil: ES(+)-HRMS m/e calculated for C11H24O2Si (M+H)+ 217.1619, found 217.1619. was added to maintain the reaction mixture basic By this point, a precipitate had formed the resulting solution was extracted into diethyl ether (2×100 mL) The combined organic extracts were washed with brine solution (150 mL) the organic layer was dried over anhydrous magnesium sulfate Filtration of the drying agent the removal of the solvent
