, p. 675 - 684 (2004)
New 20,22-mono- and 2,3:20,22-diacetals of 20-hydroxyecdyzone were synthesized, and some thereof were applied to the synthesis of 25-O-acetyl-20-hydroxyecdyzone (viticosterone E).
Synthesis of 20-hydroxyecdysone 25-acetate

, p. 57 - 60 (1997)
A scheme has been developed for the selective conjugation of 20-hydroxyecdysone (20E) at the 25-position, with the synthesis of 20E 25-acetate as an example. The proposed scheme also permits the selective synthesis of 20E 22-esters from both lower and higher fatty acids, which opens up prospects for the creation from them of drugs with a prolonged action.
PHYTOECDYSTEROIDS OF PLANTS OF THE GENUS Melandrium II. MELANDRIOSIDE A - A GALACTOSIDE OF VITICOSTERONE E FROM Melandrium turkestanicum
Saatov, Z.,Gorovits, M. B.,Abubakirov, N. K.
, p. 449 - 451 (1991)
The isolation and determination of the structure of the new phytoecdysteroid melandroside A are described; it is viticosterone E 22-O-α-D-galactopyranoside.
Selective Acetylation of 20-Hydroxyecdysone. Partial Synthesis of Some Minor Ecdysteroids and Analogues

, p. 10633 - 10650 (2007/10/02)
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.
