実験手順
Bis-1,2-{(5,6-dihydro-5,11-diketo-11H-indeno[1,2-c]isoquinoline)-(6-propyl-tert-BOCamino)}ethane (13b), N,N′-Bis(3-aminopropyl)-1,2-ethanediamine (11h) (0.16 g, 0.85 mmol) was added to a stirred solution of indenobenzopyran 4d (0.46 g, 1.87 mmol) in CHCl3 (150 mL) and the reaction mixture was stirred under reflux for 72 h, providing bisindenoisoquinoline 12 h as a crude intermediate. Upon allowing the reaction mixture to cool to room temperature, Et3N (0.6 mL, 4.24 mmol) and Boc2O (0.56 g, 2.60 mmol) were added to the reaction mixture and the mixture was allowed to stir at room temperature for 8 h. The crude reaction mixture was purified by flash column chromatography (SiO2/20% EtOAc in hexane, then 1-5% MeOH in CHCl3) to provide Boc-protected bisindenoisoquinoline 13b (550 mg, 76%) as an orange solid: mp 106-108° C. 1HNMR (CDCl3) δ 8.60 (bs, 2H), 8.23 (bs, 2H), 7.65 (bs, 2H), 7.55 (d, J=6.7 Hz, 2H), 7.40-7.32 (m, 8H), 4.48 (bs, 4H), 3.45 (bs, 8H), 2.12 (bs, 4H), 1.44 (s, 9H), 1.39 (s, 9H); ESIMS m/z (rel intensity) 835 (MH+, 22), 735 (MH+-Boc, 100). Anal. Calcd for C50H50N4O8.0.3H2O: C, 71.46; H, 6.07; N, 6.67. Found: C, 71.15; H, 6.19; N, 6.61.
