Reaction Steps
To a solution of dimethyl diazopropanedioate (4 g, 25 mmol), prepared according to Peace, Carman, Wulfman, Synthesis, 658-661, (1971), in DCM (10 mL) was added ethyl glycolate (1.2 mL, 12.8 mmol) followed by rhodium (II) acetate dimer (2 g, 20% mol). The reaction mixture was stirred at room temperature for 24 h. The resulting suspension was filtered through a pad of Celite® and the solvent was removed in vacuo. The crude residue was purified by column chromatography (silica gel) using a 0-60% EtOAc/hexanes gradient to provide the desired product as an oil (3 g, 97%).
