This paper presents a novel method for the chemical synthesis of cholest-4-ene-3,6-dione, which is a naturally occurring steroid and a potential intermediate in steroid chemistry. Pyridinium chlorochromate (PCC) in refluxing benzene has been found to be an effective and convenient reagent for the oxidation and concomitant isomerization of cholest-Δ5-en-3β-ol 3-tetrahydropyranyl ether (cholesterol tetrahydropyranyl ether) to cholest-4-ene-3,6-dione in high yield. Also described are the carbon-13 nuclear magnetic resonance spectral properties of cholest-4-ene-3,6-dione.
