General procedure: To a solution of 1 (200 mg, 0.27 mmol) and K2CO3 (55 mg, 0.40 mmol) in DMF (5 mL), the corresponding bromoalkane derivative 2 or 3 (0.33 mmol) was added under a nitrogen atmosphere and the mixture was stirred at 90C. After the completion of the reaction, water (50 mL) was added and the product was extracted with ethyl acetate (20 mL×3). The combined organic phase was dried over anhydrous Na2SO4. The crude mixture was chromatographed over silica gel column using a mixture of ethyl acetate and petroleum ether. P5-C2-Ph: white solid, in 85.6 %, m.p. 130~131 C; IR (KBr) nu/cm-1: 3050 (C=C-H), 2936, 2853, 2830 (C-H), 1600, 1497, 1469 (Ar-C=C), 1212, 1048 (C-O); 1H NMR (600 MHz, CDCl3) delta/ppm: 7.32 – 7.30 (m, 2H, C3-H,C5-H), 6.98 – 6.96 (m, 3H, C2-H, C6-H, C4-H), 6.82-6.77 (m, 10H, Ca-H), 4.27 (t, J = 6.0 Hz, 2H, C8-H), 4.15 (t, J =6.0 Hz, 2H, C7-H), 3.82 (m, 10H, Cb-H), 3.68 -3.65 (m, 24H, Cc-H), 3.56 (s, 3H, Cc-H); 13C NMR (151 MHz, CDCl3) delta/ppm: 158.95 (C-1), 151.41, 150.93, 149.82, 129.66, 128.35, 116.08, 114.82, 114.27, 114.23, 114.20, 114.13, 114.10 (C-a), 129.24 (C-3,C-5), 121.18 (C-4), 114.41 (C-2,C-6), 67.88 (C-8), 67.08 (C-7), 55.99, 55.97, 55.95, 55.92, 55.90, 55.87, 55.86, 55.77, 53.03 (C-c), 32.02 , 29.86, 29.81, 29.73, 29.68, 22.79, 14.25 (C-b); ESI-MS m/z : 856.61 ([M]+), 874.74 ([M+NH4]+), 879.75([M+Na]+); HRESI-MS m/z : calcd for C52H56O11 856.3823, found 857.3876 ([M+H]+).
The synthetic route of 589-10-6 has been constantly updated, and we look forward to future research findings.
