실험 절차

BOC-leucinol (130 mg, 0.598 mmol) was treated with 3.1 ml of 0.25 N NaOH followed by KMnO4 (125 mg, 0.796 mmol) at room temperature and stirred 15 min. The reaction was treated with methanol, stirred 15 min, and the brown precipitate removed by filtration through Celite. The filtrate was acidified with solid citric acid and extracted with ether (3×). The combined ethereal extracts were washed with saturated NaCl (aq) (2×), dried over MgSO4 and filtered. Evaporation of the filtrate in vacuo gave 130 mg of BOC-leucine as an oil homogeneous by TLC (Rf, 0.34; silica GF in 5% MeOH/95% CH2Cl2).
