Reaktionsschritte

To a solution of cyclopropylmethanol (720 mg, 10.0 mmol) in dichloromethane (20 mL) is added rhodium (II) acetate dimer (10 mg) followed by ethyl diazoacetate (0.95 mL, 9.0 mmol). The reaction mixture is stirred at rt for 5 min. The reaction mixture is diluted with heptane, filtered through Celite, and the filtrate is evaporated and the residue is vacuum distilled at 150° C. to give 1.22 g of the product 462. 1H NMR (CDCl3) δ 4.2 (q, 2H), 4.09 (s, 2H), 3.37 (d, 2H), 1.27 (t, 3H), 1.09 (m, 1H), 0.56-0.51 (m, 2H), 0.25-0.2 (m, 211); MS: m/z 191 (M+)
