实验步骤: To a round-bottom flask was added a solution of (S)-tetrahydrofuran-2-carboxylic acid (3.00 g, 25.8 mmol, 1.00 equiv) in dichloromethane (40 mL). EDC.HCl (7.50 g, 39.1 mmol, 1.50 equiv), HOBT (5.20 g, 38.5 mmol, 1.50 equiv), and hydrazine hydrate (2 mL, 2.00 equiv, 99%) were added to the reaction. The resulting solution was stirred overnight at room temperature. The solids were removed by filtration and the filtrate was concentrated in vacuo to furnish 5.38 g (80%) of the title compound as a yellow oil. The solids were removed by filtration the filtrate was concentrated in vacuo

实验步骤: To a round-bottom flask was added a solution of (S)-tetrahydrofuran-2-carboxylic acid (3.00 g, 23.3 mmol, 1.00 equiv, 90%) in dichloromethane (40 mL). NH2NH2 (2 mL, 2.00 equiv), HOBt (5.20 g, 38.5 mmol, 1.50 equiv), and EDCI (7.50 g, 39.1 mmol, 1.50 equiv) were added and the resulting mixture was stirred overnight at 25° C. The solids were removed by filtration, and the filtrate was concentrated in vacuo to furnish 2.50 g (74%) of (S)-tetrahydrofuran-2-carbohydrazide as a yellow oil. The solids were removed by filtration the filtrate was concentrated in vacuo
