실험 절차
A solution of (R)-6-allyl-3-((2S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one [Isomer 1] (450 mg, 1.41 mmol) in dry CH2Cl2 (10 mL) was treated with O3 at −78° C. till the mixture turned blue. NaBH4 (157 mg, 4.23 mmol) was added, and the mixture was stirred at rt overnight. The solution was concentrated, and the residue was purified by preparative TLC followed by preparative HPLC to give (S)-3-((S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-6-(2-hydroxyethyl)-1,3-oxazinan-2-one [Isomer 1] (265 mg, 58%). LC-MS Method 2 tR=3.83, min, m/z=669.03; 1H NMR (CDCl3): 0.71 (s, 9H), 1.06-1.11 (d, 3H), 2.07-2.19 (m, 2H), 2.31-2.28 (m, 1H), 2.67-2.76 (m, 1H), 3.12-3.18 (m, 1H), 3.47-3.58 (m, 1H), 3.69-3.78 (m, 1H), 4.38-4.47 (m, 1H), 7.03-7.09 (m, 2H), 7.26-7.33 (m, 2H).
