実験手順

A solution of #114 (447 mg, 0.707 mmol, 1.0 eq.) in 2 mL of dichloromethane was added to a solution of N-[(9H-fluoren-9-ylmethoxy)carbonyl]-D-isovaline (240 mg, 0.707 mmol, 1.0 eq.) in 4 mL of dichloromethane. Hunig's base (0.373 mL, 2.12 mmol, 3 eq.) was added followed by HATU (332 mg, 0.425 mmol, 1.2 eq.). The reaction was allowed to stir at room temperature for 12 hours. The reaction was concentrated in vacuo and then taken up in ethyl acetate before being washed two times with 1M HCl and once with brine. The organic layer was dried over sodium sulfate and decanted. The organic solvent was removed in a genevac. THF (4 mL) was added followed by diethylamine (2 mL, 19 mmol, 26.9 eq.). The reaction was allowed to stir for ˜12 hours. Reaction was concentrated using a genevac followed by silica chromatography (Gradient: 0%-30% methanol in ethyl acetate) producing #149 (154 mg, 30%) as a solid. LC-MS (Protocol Q): m/z 732.0 [M+H+] retention time=1.24 minutes. 1H NMR (400 MHz, DMSO-d6), δ 8.55 (d), 8.38-8.46 (m), 8.29 (d), 8.03-8.14 (m), 7.97 (d), 7.81 (d), 7.40-7.53 (m), 7.14-7.28 (m), 7.02 (s), 4.71-4.79 (m), 4.43-4.69 (m), 3.96-4.05 (m), 3.71-3.80 (m), 3.62-3.70 (m), 3.49-3.60 (m), 3.40-3.48 (m), 3.15-3.34 (m), 3.10-3.14 (m), 3.01-3.09 (m), 2.94-3.00 (m), 2.83-2.93 (m), 2.65-2.71 (m), 2.55-2.59 (m), 2.32-2.48 (m), 2.04-2.31 (m), 1.61-1.89 (m), 1.37-1.52 (m), 1.21-1.35 (m), 1.15-1.20 (m), 1.02-1.10 (m), 0.75-1.01 (m).
