実験手順
Ester 50.4 (48 mg, 0.09 mmol) was dissolved in dichloromethane/TFA solution (3:1, 2 mL). The resulting mixture was stirred at room temperature for 2 h. The solvent removed under reduced pressure, and the product was purified on reserve phase HPLC to yield acid 50 (30 mg). MS ESI (pos.) m/e: 472 (M+H). 1H NMR (400 MHz) (CDCl3) δ 7.72 (4H, s); 7.67 (1H, s); 7.59-7.28 (3H, m); 7.2 (2H, d, J=8.6 Hz); 7.0 (2H, d, J=8.6 Hz); 5.13 (2H, s); 4.24-4.21 (1H, m); 3.20-3.13 (1H, m); 3.0 (3H, s); 2.95 (3H, s); 2.76-2.71 (1H, m).
