Reaktionsschritte

To a solution of 3-carboxycyclopentanone (640 mg, 5.0 mmol) in 8 mL of degassed DMF was added potassium carbonate (828 mg, 5.99 mmol) and benzyl bromide (0.65 mL, 5.49 mmol). After 4 hours at room temperature, the reaction mixture was poured into 50 mL of water and extracted 3 times with EtOAc. The combined organic layers were washed with water and dried over sodium sulfate. Filtration and solvent removal provided material that was subjected to silica gel chromatography eluting with 10% EtOAc in hexanes to yield benzyl 3-oxocyclopentanecarboxylate.
