Dimethyl Sulfoxide → HCID 15037104, compound

Participants

Reaction Steps

A mixture of dimethyl sulfoxide (0.9 ml) and dichloromethane (9 ml) was added to a solution of oxalyl chloride (0.64 ml, 7.39 mmol) at -78 degrees under argon. After 5 minutes, a solution of 3-(2-triethylsilyl-4-furyl)propan-1-ol (1.27 g, 5.28 mmol) in dichloromethane (9.0 ml) was added dropwise and after 20 minutes, triethylamine (2.9 ml, 21.1 mmol) was added. Stirring was continued at -78 degrees C. for 40 minutes and at room temperature for 3 hours. The mixture was quenched with water and was extracted thoroughly with ethyl ether. Evaporation of the dried (magnesium sulfate) extracts gave an oil, which was purified by a silica column to give the titled aldehyde.
