Methyl morpholine oxide → 4-Phenyl-3-furaldehyde

Participants

Reaction Steps

A mixture of 3-phenyl-4-furylmethanol (Compound 19, 458 mg, 2.63 mmol), powdered 4A molecular sieves (500 mg), 4-methyl-morpholine-N-oxide (462 mg, 3.95 mmol) and tetrapropylammonium perruthenate (46 mg, 0.13 mmol) in anhydrous dichloromethane (40 ml) were stirred at room temperature for 3 hours. Residue was filtered through silica and concentrated to a brown oil which was purified by flash chromatography on silica using 10% ethyl ether/hexanes to give the titled aldehyde.
