%X The possible ecdysteroid precursors 3&#946;,5,14x-trihydroxy-5&#945;-cholest-7- en-6-one (12) and 3&#946;,14&#945;-dihydroxycholesta-4,7-dien-6-one (19) have been synthesized and the metabolism of the corresponding 3&#945;-tritium- labelled compounds studied in Calliphora stygia at the time of ecdysteroid biosynthesis. Labelled 20-hydroxyecdysone was isolated in both cases and the compounds may thus be ecdysteroid precursors. However, confirmation of these results with substrates labelled in another position is necessary.
