PROCEDURE

实验过程

750 mg. of 17α-ethinyl-11β-fluoro-17β-hydroxy-4,6-androstadien-3-one in 50 ml. of ethylene chloride is combined with 1.2 g. of m-chloroperbenzoic acid in 5 ml. of tert.-butanol and 1 ml. of ethylene chloride. The mixture is agitated at room temperature for 21 hours. The solution is then diluted with ethyl acetate and washed successively with sodium bisulfite solution and water. In this way, 420 mg. of 17α-ethinyl-6α,7α-epoxy-11β-fluoro-17β-hydroxy-4-androsten-3-one is isolated. UV: ε239 = 16,300 (methanol).
