실험 절차
Diazoacetic acid ethyl ester (80.00 g, 0.70 mol) was added dropwise to cyclopropanemethanol (60.66 g, 0.84 mol) and [Rh(Ac2O)2]2 (3.1 g, 7.02 mmol) in anhydrous CH2Cl2 (800 mL) at 0° C. The mixture was stirred at 0° C. for 30 min and at room temperature for 4 h. CH2Cl2 extractive work up and silica gel chromatography (PE:EA=100:1-50:1) gave the title compound (100 g, 90.4% yield) as a colorless oil. 1H NMR: (CDCl3, 400 MHz) δ 4.23-4.19 (m, 2H), 4.09 (s, 2H), 3.38-3.36 (m, 2H), 1.27 (t, J=7.2 Hz, 3H), 1.10-1.07 (m, 1H), 0.57-0.52 (m, 2H), 0.24-0.20 (m, 2H).
