实验步骤: 1-Hydroxypyrrolidine-2,5-dione (1.18 g, 10.3 mmol), cyclopropanecarboxylic acid (1.01 ml, 10 mmol), EDC (2.01 g, 10.5 mmol) and Et3N (2.8 mmol, 20 mmol) in DCM were stirred at rt for 5 h before it was partitioned with saturated NH4Cl solution. The organic layer was washed with brine and dried over Na2SO4. After filtration and concentration, 2,5-dioxopyrrolidin-1-yl cyclopropanecarboxylate 24 was isolated and used without further purification. was partitioned with saturated NH4Cl solution The organic layer was washed with brine dried over Na2SO4 After filtration and concentration
