実験手順
To a solution of compound 57 (0.5 mmol) in anhydrous DMF was added 3-bis(benzyloxy)phosphorylpropanoic acid (0.75 mmol) and EDC (0.75 mmol) and DMAP (catalytic amount). The reaction mixture was stirred at room temperature overnight. Solvent was removed in vacuo. To the residue, 100 mL ethyl acetate was added. The organic layer was washed with water, and dried with MgSO4. Solvent was removed to afford a colorless oil, which was recrystallized in EtOAc/Hexanes to afford a white solid 58 in 40% yield. MS (ES−): 581; Mp: 173-175° C. 1H-NMR (CDCl3, 400 MHz): 10.01 (s, 1H), 8.11 (d, J=2.0 Hz, 1H), 8.07 (d, J=7.5 Hz, 1H), 7.82 (t, J=8.5 Hz, 1H), 7.54 (d, J=8.0 Hz, 1H), 7.40 (dd, J=8.5 and 2.0 Hz, 1H), 7.35-7.22 (m, 11H), 5.09 (s, 2H), 4.98 (m, 4H), 2.62 (m, 2H), 2.12 (m, 2H); Anal: Calcd for C32H27N2O7P: C, 65.98; H, 4.67; N, 4.81. Found: C, 65.69; H, 4.82; N, 5.09.
