Аннотация:
9α,14α-Epoxy-14-deoxy-20-hydroxyecdysone diacetonide on treatment with NaBH4 undergoes reduction of 6-keto group and cleavage of allylic oxetane ring, the 6-keto reduction is accompanied by β→α epimerization of the adjacent HC5 centre. Subsequent re-oxidation of the 6-CHOH fragment into ketone with pyridinium chlorochromate and acidic deprotection affords 25-hydroxydachryhainansterone possessing β-HC5 configuration due to the re-epimerisation at this centre.
Ключевые слова:
ecdysteroids, oxetane cycle,
7,9-dien systeme, 25-hydroxydachryhainansterone.
