TCI Practical Example: Olefin Metathesis Using nitro-Grela

Used Chemicals


In a 200 mL two necked round bottomed flask, nitro-Grela (15 mg, 22 µmol) was added, and purged with N2. Dichloromethane (40 mL) was charged in the flask, and diethyl diallylmalonate (237 mg, 986 µmol) in dichloromethane (5.5 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 (206 mg, 98%).

Experimenter's Comments

The reaction mixture was monitored by NMR.

Analytical Data(Diethyl cyclopent-3-ene-1,1-dicarboxylate)

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).

Experimental procedure2): A mixture of 1 (25.0 mg, 69.3 µmol) and nitro-Grela (929 µg, 1.39 µmol) in CH2Cl2 (3.5 mL) is stirred at room temperature for 2 h. The mixture is concentrated to give a residue, which is subjected to column chromatography on silica gel. Elution with hexane:ethyl acetate (10:1) gives 2 (15.6 mg, 74% yield) as a colorless oil.
