PROCEDURE

实验过程

The procedure of Example 6 was repeated except that 140 mg of 1α,3β-bis(t-butyldimethylsilyloxy)pregna-5,7-diene-20-carbaldehyde was used in lieu of 120 mg of 1α,3β-bis(methoxycarbonyloxy)pregna-5,7-diene-20-carbaldehyde to give 112 mg of 1α,3β-bis(t-butyldimethylsilyloxy)pregna-5,7-diene-20-carboxylic acid.
