실험 절차

To a solution of 4-allyloxybenzaldehyde (1.0 g, 6.17 mmol) in acetone (40 mL) and water (5 mL) is added a 2.5% solution of OsO4 in tert. butanol (1.25 mL) followed by N-methyl morpholine-N-oxide (867 mg, 7.4 mmol). The pale yellow solution is stirred at rt for 6 h, diluted with EA (250 mL) and washed with 10% aq. citric acid solution (100 mL) and water (2×100 mL). The washings are extracted with EA (150 mL). The combined organic extracts are concentrated and purified by column chromatography on silica gel to give the title compound (731 mg) as a turbid oil. The title compound reversibly polymerizes upon standing. LC-MS: tR=0.58 min, [M+1+CH3CN]+=238.
