α,β,γ,δ-Unsaturated carbonyl compounds were converted regioselectively into γ-hydroxy-α,β-unsaturated carbonyl compounds by reduction-oxygenation with molecular oxygen and triethylsilane in the presence of cobalt(II) porphyrin as a catalyst followed by treatment with trimethyl phosphite. (±)-Hydroxyshogaol and related furanoids isolated from ginger were synthesized via this method.

A simple one-pot reaction which converts acids into urethanes is described.Acyl chlorides are converted into isocyanates under anhydrous conditions by sodium azide in the presence of a quaternary ammonium salt, followed by alcohol addition to complete the transformation.
