Procedure

To 4-(5-oxo-3-hexadecenyl)-2-trimethylsilylfuran (98 mg, 0.261 mmol), prepared as in Example 3, in ethyl acetate (2 ml) was added platinum oxide (10 mg, 0.044 mmol). This mixture was subjected to one atmosphere of hydrogen at room temperature with stirring for 21/2 hours. The reaction mixture was filtered and concentrated to give a yellow oil. Purification by flash chromatography (silica, 3% ethyl ether/hexane) gave the desired ketone.
