实验步骤: To a solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxylic acid 1 (0.2 g, 0.72 mmol) in dry DCM (20 mL) were added (aminooxy)cyclohexane 21 (0.1 g, 0.86 mmol, US 2008/146625 A1), 1-hydroxybenzotriazole (0.14 g, 1.1 mmol) and 1-ethyl-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.2 g, 1.1 mmol) at room temperature. The reaction mixture was stirred at room temperature overnight, and then concentrated under vacuum. The residue was purified by column chromatography to give (2S,5R)-6-(benzyloxy)-N-(cyclohexyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-carboxamide 22 (0.24 g, 89.5%) as a clear thick oil. concentrated under vacuum The residue was purified by column chromatography
