- 論文の詳細を見る
3-Enol acetates of some 4-en-3-oxo-steroids were oxidized to the corresponding 7-ones with t-butyl chromate and 3-enol methyl ethers were to the corresponding 4-ene-3,6-diones, 6β-hydroxy-4-en-3-ones or 4,6-dien-3-ones according to the reaction conditions. 3-Enol methyl ethers were prepared with methyl orthoformate in dioxane by catalysis of p-toluenesulfonic acid. 17α-Acetoxy-5α, 6β-dichloropregnane-3,20-dione was converted into 3-methoxy-6-chloro-17α-acetoxypregna-3,5-dien-20-one in one step.
