实验过程

The procedure of Example 24 was repeated except that 3.4 mg (0.00887 mmole) of 20-(1,3-dioxolan-2-yl)-1α,2α-epoxypregna-5,7-dien-3β-ol was used in lieu of 3.8 mg of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregna-5,7-dien-3β-ol to give 2.7 mg of 20-(1,3-dioxolan-2-yl)pregna-5,7-diene-1α,3β-diol (yield: 78%).
