실험 절차

Into 35 ml of glacial acetic acid at 60°-70° C. is dropped slowly 12.4 g. (0.1 mole) of 1-diazo-5-hexen-2-one. After the nitrogen evolution stops, the reaction mixture is heated to reflux for one hour. The resulting mixture is extracted with 3×50 ml of methylene chloride. The organic layer is dried over anhydrous magnesium sulfate. Concentration of the filtrate gives 1-acetoxy-5-hexen-2-one as a brown oil in 90% yield, based on the starting 4-pentenoyl chloride.
