実験手順
Methyl oleate (1) (5.0 g; 0.017 mol) (89%) (ITERG) and meta-chloroperbenzoic acid (mCPBA) (4.3 g; 0.025 mol) (Aldrich) were dissolved in dichloromethane (J. T. Baker) (100 mL) and the reaction mixture was mixed under agitation at ambient temperature for 5 hours. The reaction mixture was then filtered and the collected solution was washed with saturated aqueous sodium bicarbonate (3×50 mL) (Aldrich) then with water (3×50 mL). The organic layer was separated and dried over anhydrous sodium sulfate. Finally, the solvent was removed by evaporation under rotation to obtain the intermediate compound 2.
