Procedure

3-(4-Iodophenyl)-2-oxopropyl nitrate (17) (450 mg) was dissolved in dimethylsulfoxide (20 mL) and to this was added sodium acetate trihydrate (211 mg, 1.55 mmol), and stirred for an hour at room temperature. To this was added water and the product was extracted with diethyl ether (×3). The organic layer was washed sequentially with water (×1), saturated aqueous solution of sodium bicarbonate (×1) and saturated brine (×1), and then dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to give 3-(4-iodophenyl)-2-oxopropanal (18) as an orange solid (346 mg, <1.26 mmol, <90.1%), which was used in the next reaction without further purification.
