実験手順

To a solution of #50 (120 mg, 0.18 mmol, 1 eq.), Brop (84 mg, 0.21 mmol, 1.2 eq.) and diisopropylethylamine (0.1 mL, 0.54 mmol, 3 eq.) in dichloromethane (15 mL, 0.009 M) at 0° C. was added 1-aminocyclohexanecarboxylic acid (31 mg, 0.21 mmol, 1.2 eq.). After 2 hours, the mixture was quenched with water and extracted twice with ethyl acetate. The combined organic layers were dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified by silica gel chromatography (Gradient: 0% to 5% methanol in dichloromethane) to give #52 (50 mg, 35%). Rf 0.6 (10% methanol in dichloromethane). LC-MS (Protocol K): m/z 783.79 [M+H+]; 1H NMR (400 MHz, DMSO-d6), presumed to be a mixture of rotamers, characteristic signals: δ [8.64 (br d, J=8 Hz) and 8.87 (br d, J=9 Hz), total 1H], 8.18-8.28 (m, 1H), [7.77 (d, J=3.5 Hz) and 7.80 (d, J=3.3 Hz), total 1H], [7.63 (d, J=3.3 Hz) and 7.66 (d, J=3.3 Hz), total 1H], 7.12-7.31 (m, 5H), 5.35-5.43 and 5.49-5.57 (2 m, total 1H), [4.51 (dd, J=9, 8 Hz), and 4.61 (dd, J=9, 7 Hz), total 1H], 3.16, 3.19, 3.21 and 3.25 (4 s, total 6H), 2.93 and 3.02 (2 br s, total 3H), [1.05 (d, J=6.8 Hz) and 1.10 (d, J=6.8 Hz), total 3H].
