PROCEDURE

实验过程

A second method of preparing βAET has been developed which also used 3β,17β diacetoxyandrost-5-ene as a starting material as before. This compound was oxidized with t-butylhydroperoxide in the presence of chromium hexacarbonyl (Cr(CO)6) to form 3β,17β-diacetoxyandrost-5-en-7-one as described by Pearson [Pearson, et al., J. Chem Soc. Perkin Trans. I, 267 (1985)]. The enone formed then was reduced with triisobutylaluminum (TIBA) to give the acetylated 7β-hydroxy (I) product.
