N2  - The possible biological precursors of ecdysones, 3&#946;-hydroxy-5&#946;-cholest-7-en-6-one (2) and 3&#946;,14&#945;-dihydroxy-5&#946;-cholest-7-en-6-one (3), are prepared from 7-dehydrocholesterol through their 5&#945;-epimers.The corresponding 3&#945;-[3H] derivatives of high specific activity are prepared in a similar way via 5&#945;-cholest-7-ene-3&#946;,6&#945;-diol[3&#945;-3H] 6-acetate which is obtained by reducing the corresponding 3-keto derivative with sodium borotritide.
