With dmap; In dichloromethane; at 20℃; for 12.0h; EXAMPLE 1.3. Synthesis of an M3 type compound of substituent 1 (8 in this Example); The carbonate 7 was prepared by reacting the disulfide 4 with bis(4-nitrophenyl) carbonate (Fardis, M.; Pyun, H.-J.; Tario, J.; Jin, H.; Kim, C. U.; Ruckman, J.; Lin, Y.; Green, L.; Hicke, B. Bioorg. Med. Chem. 2003, 11, 5051-5058.). Treatment of paclitaxel with 7 gave the M3 type paclitaxel disulfide 8 (Liu, C; Schilling, J. K.; Ravindra, R.; Bane, S.; Kingston, D. G. I. Bioorg. Med. Chem. 2004, 12, 6147-6161.); Synthesis of compound 8.; A solution of the disulfide 4 (see Senter, P. D.; Pearce, W. E.; Greenfield, R. S. /. Org Chem. 1990, 55, 2975-2978) (7 mg, 28 mumol) in dry dichloromethane (2 mL) was added to a stirred solution of bis(4-nitrophenyl) carbonate (12.8 mg, 42 mumol) and 4-(dimethylamino) pyridine (10.3 mg, 84 mumol) in dry <n="54"/>dichloromethane (2 mL). After being stirred at room temperature for 12 h, paclitaxel (47.8 mg, 56 mumol) was added. The reaction mixture was allowed to stir at room temperature for another 12 h (see Fardis, M.; Pyun, H.-J.; Tario, J.; Jin, H.; Kim, C. U.; Ruckman, J.; Lin, Y.; Green, L.; Hicke, B. Bioorg. Med. Chem. 2003, 11, 5051-5058; Liu, C; Schilling, J. K.; Ravindra, R.; Bane, S.; Kingston, D. G. I. Bioorg. Med. Chem. 2004, 12, 6147-6161.) Workup as described above and purification by preparative TLC (30% EtOAc/hexanes) afforded compound 8 (25.3 mg, 80%): 1H NMR (CDCl3). delta 8.48 (IH, d, / = 4.6 Hz), 8.13 (2H, d, J = 8.0 Hz), 7.71 (2H, d, / = 8.3 Hz), 7.25-7.65 (17H, m), 7.13 (IH, br dd, / = 5.1, 3.3 Hz), 6.88 (IH, d, J = 9.2 Hz), 6.29 (2H, br s), 5.97 (IH, br d, / = 9.2 Hz), 5.68 (IH, d, / = 7.0 Hz), 5.42 (IH, br s), 5.13 (IH, d, / = 12.3 Hz), 5.09 (IH, d, / = 12.3 Hz), 4.97 (IH, d, / = 9.4 Hz), 4.43 (IH, dd, J = 10.6, 6.9 Hz), 4.31 (IH, d, / = 8.5 Hz), 4.20 (IH, d, / = 8.5 Hz), 3.80 (IH, d, J = 7.0 Hz), 2.56 (IH, m), 2.44 (3H, s), 2.39 (IH, dd, J = 15.4, 9.4 Hz), 2.23 (3H, s), 2.19 (IH, dd, J = 15.4, 8.7 Hz), 1.91 (3H, s), 1.88 (IH, m), 1.68 (3H, s), 1.25 (3H, s), 1.13 (3H, s); 13C NMR (CDCl3) delta 203.8, 171.3, 169.8, 167.8, 167.1, 167.1, 159.2,154.0, 149.6, 142.6, 137.4, 136.6, 133.6, 133.4, 133.4, 132.8, 132.1, 130.2, 129.1, 129.1,129.1, 128.7, 128.7, 128.5, 127.4, 127.1, 126.5, 121.1, 119.8, 84.4, 81.1, 79.2, 77.2, 76.9, 76.4, 75.6, 75.1, 72.1, 72.1, 70.0, 58.5, 52.7, 45.6, 43.2, 35.6, 35.6, 26.8, 22.7, 22.2, 20.8, 14.8, 9.6; HRFABMS m/z 1129.3433 [M + H+] (calcd for C60H6IN2Oi6S2, 1129.3463).

YieldReaction ConditionsOperation in experiment
91% With pyridine; dmap; In dichloromethane; at 0 - 20℃; for 2.0h; To a stirred solution of (4-(pyridin-2-yldisulfanyl)phenyl)methanol (0.40 g, 1.60 mmol) in CH2CI2 (10 mL) were added 4-nitrophenyl chloroformate (0.65 g, 3.2 mmol), pyridine (0.25 mL, 3.20 mmol), catalytic amount of DMAP (0.005 g ) at 0C. The mixture was allowed to stir for 2 h at room temperature. The reaction mixture was quenched with 1.5 N HC1 solution. The organic layer was separated and washed with brine, dried over anhydrous Na2SCri and concentrated. The crude product was purified by columnchromatography (S1O2, 20-30% of EtO Ac/hexanes) to afford (4-nitrophenyl) [4-(2- pyridyldisulfanyl)phenyl] methyl carbonate as a colourless liquid (600 mg, 91% yield); MS m/z 415.0 [M+H]+
