実験手順
To a solution of (2R,3S)-2-(3-phenyl-1-propyl)-3-(formyl-2-tetrahydropyrariyloxyamino)butanoic acid (120 mg, 0.344 mmol) in DMF (1 mL) is added BOP reagent (167 mg, 0.378 mmol), HOBt (51 mg, 0.378 mmol), and NMM (174 mg, 1.72 mmol). After 30 min, (2S)-2-amino-3,3-dimethylbutanoic acid 3-pyridylamide dihydrochloride (118 mg, 0.410) is added and the resulting solution is stirred at 25° C. for 18 h. The reaction mixture is concentrated, diluted with EtOAc (20 mL) and washed sequentially with 1 M aqueous sodium carbonate and saturated aqueous sodium chloride. The organic layer is dried over magnesium sulfate, concentrated in vacuo, and purified by silica gel chromatography (elution with 2:1 EtOAc-hexane) to provide (2R,3S)-3-(formyl-2-tetrahydropyranyloxyamino)-2-(3-phenyl-1-propyl)butanoic acid [(1S)-2,2-dimethyl-1-(3-pyridylcarbamoyl)-1-propyl]amide as a solid (115 mg, 62% yield). ESI-MS m/z 529 (M+H)+.
