Reaktionsschritte
To a solution of 2-propanol (0.776 mL, 10.0 mmol) in dichloromethane (33 mL) is added rhodium (II) acetate dimer (22 mg) followed by ethyl diazoacetate (1.05 mL, 10.0 mmol). The reaction mixture is stirred at RT for 30 min. The reaction mixture is filtered through Celite, and the filtrate is evaporated and the residue is vacuum distilled at 150° C. to give 750 mg of the product 405. 1H NMR (CDCl3) δ 4.21 (q, 2 H), 4.06 (s, 2 H), 3.73 (m, 1 H), 1.29 (t, 3 H), 1.22 (s, 3 H), 1.19 (s, 3 H); MS: m/z 147 (M++1).
