实验过程
The procedure of Example 23 was repeated except that 4.6 mg (0.0106 mmole) of 1α,2α-epoxy-21,21-dimethoxy-20-methylpregna-5,7-dien-3β-yl acetate was used in lieu of 5 mg of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregna-5,7-dien-3β-yl acetate to give 3.5 mg of 1α,2α-epoxy-21,21-dimethoxy-20-methylpregna-5,7-dien-3β-ol (yield: ca. 85%).
