Selective acetylation of the 2:3- and 20:22-acetonide and 2:3:20,22-diacetonide derivatives of 20-hydroxyecdysone and subsequent removal of the protecting groups led to partial synthesis of a number of mono-, di- and triacetate derivatives of 20-hydroxyecdysone. Some of these acetate derivatives are minor, naturally occurring ecdysteroids.
