实验步骤: To a round-bottom flask was added a solution of (R)-tetrahydrofuran-2-carboxylic acid (3.00 g, 25.8 mmol, 1.00 equiv) in dichloromethane (60 mL). EDC.HCl (7.37 g, 38.5 mmol, 1.50 equiv), HOBt (5.24 g, 38.8 mmol, 1.50 equiv), and hydrazine hydrate (2.60 g, 51.9 mmol, 2.00 equiv) were added to the reaction. The resulting solution was stirred overnight at 25° C. The solids were removed with filtration. The filtrate was concentrated in vacuo to yield 2.00 g (59%) of (R)-tetrahydrofuran-2-carbohydrazide as a yellow oil. The solids were removed with filtration The filtrate was concentrated in vacuo
