실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer was charged with 107a (77 mg, 1.0 eq., 0.11 mmol), NaBH4 (21 mg, 5.0 eq., 0.55 mmol), and MeOH (10 mL). The mixture was stirred at room temperature for 1 h. It was then filtered and the filtrate was concentrated. The residue was purified by reverse-phase prep-HPLC to afford 107 (38 mg, 49%). MS: [M+H]+ 698.3. 1H NMR (500 MHz, CDCl3) δ 8.59 (d, J=2.0 Hz, 1H), 8.29 (d, J=2.5 Hz, 1H), 7.98 (d, J=2.5 Hz, 1H), 7.81 (s, 1H), 7.56-7.54 (m, 2H), 7.40 (s, 1H), 7.31-7.27 (m, 2H), 7.11-7.10 (m, 1H), 6.81 (d, J=9.0 Hz, 1H), 4.71-4.62 (m, 4H), 4.35 (s, 2H), 3.73-3.70 (m, 4H), 3.53-3.46 (m, 2H), 3.08 (t, J=5.0 Hz, 2H), 2.56-2.46 (m, 3H), 2.22-2.18 (m, 1H), 1.43 (s, 9H), 0.98 (d, J=6.5 Hz, 3H).
