実験手順
To a solution of cyclohexanol (1.0 g, 0.95 mmol) in dichloromethane (30 mL) is added rhodium (II) acetate dimer (44 mg) followed by ethyl diazoacetate (1.14 g, 10.0 mmol). The reaction mixture is stirred at RT for 20 min. The reaction mixture is diluted with Et2O, filtered through Celite, and the filtrate is evaporated and the residue is vacuum distilled at 150° C. to give 1.57 g of the product 407. 1H NMR (CDCl3) δ 4.23 (q, 2H), 4.10 (s, 2H), 3.33 (m, 1H), 1.93 (m, 2H), 1.74 (m, 2H), 1.54 (m, 1H), 1.4-1.1 (m, 8H)
