abstract：:The polyhydroxy structure of ecdysteroids provides a basis for the formation of various derivatives including the acetonides that have been frequently prepared mainly in preparative work. Acetonides can be formed between vicinal diols in cis position such as positions C-2/C-3 and C-20/C-22 in 20-hydroxyecdysone, for e...
