Versuchsvorschrift

To a solution of benzyl alcohol (1.04 mL, 10.0 mmol) in dichloromethane (30 mL) is added rhodium (II) acetate dimer (40 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 rotary evaporated, and the residue is vacuum distilled at 110° C. to give 1.81 g of the product 390. 1H NMR (CDCl3) δ 7.4-7.26 (m, 5H), 4.65 (s, 2H), 4.23 (q, 2H), 4.10 (s, 2H), 1.30 (t, 3H).
