PROCEDURE

实验过程

The procedure of Example 26 was repeated except that 0,426 g (1.0 mmole) of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,2α-epoxypregna-4,6-dien-3-one was used in lieu of 0.410 g of 20-(5,5-dimethyl-1,3-dioxan-2-yl)pregna-1,4,6-trien-3-one to give 0.205 g of 1α,2α-epoxy-3-oxopregna-4,6-diene-20-carbaldehyde (yield: 60%).
