The β-epoxidation of 3β-acetoxy-Δ⁵-unsaturated steroids has been achieved with numerous potassium permanganate-metal sulphates and nitrates with a high degree of stereoselectivity. 5β,6β-Epoxides are formed in a one step reaction in good yields and using very low cost reagents. The best results were achieved with KMnO₄/Fe₂(SO₄)₃.nH₂O.
