实验过程
The procedure of Example 36 was repeated except that 2.2 mg (0.005 mmole) of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregna-5,7-dien-3β-ol was used in lieu of 2.2 mg of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregn-5-ene-3β,7α-diol to give 1.0 mg of 1α,2α-epoxy-3β-hydroxypregna-5,7-diene-20-carbaldehyde (yield: 58%).
