实验过程

The procedure of Example 6 was repeated except that 4.16 g (11.3 mmoles) of 20-(1,3-dioxolan-2-yl)pregna-1,4,6-trien-3-one was used in lieu of 4.66 g of 20-(5,5-dimethyl-1,3-dioxan-2-yl)pregna-1,4,6-trien-3-one to give 3.25 g of 20-(1,3-dioxolan-2-yl)-1α,2α-epoxypregna-4,6-dien-3-one (yield: 75%).
