4-(5-Hydroxy-3-hexadecynyl)-2-triethylsilylfuran → 4-(5-Oxo-3-hexadecynyl)-2-triethylsilylfuran

Participants

Reaction Steps

Jones reagent (a 2.6M solution in sulfuric acid; 0.13 ml, 0.36 mmol) was added dropwise to a solution of 4-(5-hydroxy-3-hexadecynyl)-2-triethylsilylfuran (136.4 mg, 0.33 mmol) in acetone (5 ml) at 0 degrees. After 20 minutes, the excess Jones reagent was destroyed with ethanol (ca 1 ml) and the mixture was diluted with water. The organic phase was is separated, dried (magnesium sulfate) and evaporated down to give an oil, which was purified by preparative silica plates to give the titled ketone.
