실험 절차

To a solution of COMPOUND 282 (47 mg, 0.089 mmol) in MeOH (4 mL) was added methoxylamine hydrochloride (19 mg, 0.22 mmol) and NaOAc (21 mg, 0.25 mmol) and the mixture was stirred at room temperature overnight. Standard work-up and purification afforded COMPOUND 283 as a white solid (38 mg, 75%). 1H NMR (CDCl3) δ 0.76-0.81 (m, 1H), 0.94 (d, 3H, J=6.6 Hz), 1.01-1.06 (m, 1H), 1.45-1.75 (m, 4H), 1.88-1.96 (m, 2H), 2.19 (s, 3H), 2.37 (t, 1H, J=10.7 Hz), 2.51 (s, 6H), 2.66-2.82 (m, 3H), 3.22-3.30 (m, 1H), 3.84-3.94 (m, 1H), 3.98 (s, 3H), 6.75-6.78 (m, 2H), 6.84-6.87 (m, 1H), 6.93-6.96 (m, 1H), 7.37 (d, 2H, J=8.4 Hz), 7.61 (d, 2H, J=8.4 Hz), 8.82-8.83 (m, 1H), 9.08 (s, 1H). 13C NMR (CDCl3) δ 12.63, 13.18, 21.54, 21.89, 25.60, 26.25, 30.62, 40.22, 43.57, 45.17, 52.24, 60.78, 61.77, 62.00, 108.53, 108.63, 117.87, 121.39, 125.35, 125.69, 125.79, 127.78, 130.82, 137.07, 140.48, 147.05, 147.16, 154.18, 157.68, 162.88, 166.51.
