実験手順

To a mixture of cyclohexanol (2.40 g, 24.0 mmol) and Rh2(OAc)4 (50 mg, 0.11 mmol) in DCM (50 mL) was added ethyl 2-diazoacetate (2.73 g, 23.9 mmol) and the mixture was stirred at rt for 5 min. It was then filtered and the filtrate was concentrated in vacuo. The residue was purified by a silica gel column chromatography (PE/EtOAc (V/V)=15:1) to give the title compound as colorless oil (3.8 g, 85%).
