Abstract
The possible biological
precursors of ecdysones, 3β-hydroxy-5β-cholest-7-en-6-one
(2) and 3β,14α-dihydroxy-5β-cholest-7-en-6-one (3), are prepared
from 7-dehydrocholesterol through their 5α-epimers.The corresponding 3α-[3H]
derivatives of high specific activity are prepared in a similar way via
5α-cholest-7-ene-3β,6α-diol[3α-3H] 6-acetate
which is obtained by reducing the corresponding 3-keto derivative with sodium
borotritide.
