Reaction Steps
To a solution of cycloheptanol (0.600 mL, 5.0 mmol) in dichloromethane (15 mL) is added rhodium (II) acetate dimer (21 mg) followed by ethyl diazoacetate (0.60 g, 5.7 mmol). The reaction mixture is stirred at RT for 10 min. The reaction mixture is rotary evaporated, and the residue dissolved in Et2O, filtered through Celite, and the filtrate is evaporated and the residue is vacuum distilled at 150° C. to give 0.960 g of the product 411. 1H NMR (CDCl3) δ 4.21 (q, 2H), 4.06 (s, 2H), 3.50 (m, 1H), 1.93 (m, 2H), 1.7-1.4 (m, 8H), 1.4-1.3 (m, 2H), 1.28 (t, 3H); MS: m/z 201 (M++1).
