PROCEDURE

实验过程

The reaction and workup procedures of Example 156 were repeated except that 100 mg of 21,21-dimethoxy-20-methyl-pregna-5,7-diene-1α,3β-diol was used in lieu of 100 mg of 20-(5,5-dimethyl-1,3-dioxan-2-yl)-1α,3β-bis(methoxycarbonyloxy)pregna-5,7-diene to give 45 mg of 1α,3β-dihydroxypregna-5,7-diene-20-carbaldehyde showing the following physical properties.
