Magnesium monoxide → 2-Oxa-4-azatetracyclo[6.3.1.16,10.01,5]tridecan-3-one

Tricyclo[3.3.1.13,7]dec-1-yl carbamate (100 mg, 0.512 mmol), iodobenzenediacetate (220 mg, 0.683 mmol), magnesium oxide (50 mg, 1.24 mmol) and rhodium (II) acetate dimer (22 mg, 0.050 mmol) were stirred in dichloromethane (3 mL) at 50° C. for 5 hours. After completion of the reaction, the reaction solution was filtered, and the solid was washed with chloroform and the filtrate was evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1→2/1) to give the desired product (77% yield).
