In a 200 mL two necked round bottomed flask, AquaMet (50 mg, 52 μmol) was added, and purged with N2. Dichloromethane (100 mL) was charged in the flask, and diethyl diallylmalonate (500 mg, 2.08 mmol) in dichloromethane (20 mL) was added dropwise and the mixture was stirred at room temperature for 6 h. The solvent was removed under reduced pressure and the residue was purified by silica-gel column chromatography (hexane : EtOAc = 1 : 1) to give diethyl cyclopent-3-ene-1,1-dicarboxylate as a pale yellow oil (430 mg, 98%).
The reaction mixture was monitored by NMR.
1H NMR (400 MHz, CDCl3); δ 5.61 (s, 2H), 4.20 (q, J = 8.0 Hz, 4H), 3.01 (s, 4H), 1.25 (t, J = 8.0 Hz, 6H).
