Synthesis of 20-hydroxyecdysone 25-acetate

Chemistry of Natural Compounds, 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 ...

20-hydroxyecdysone oximes and their rearrangement into lactams

Russian Journal of Organic Chemistry, 2009
(E)-Oximes derived from 20-hydroxyecdysone diacetonides and 7,8-dihydro analog were converted into the corresponding lactams (6-oxo-5a-aza-5a-homo derivatives) via Beckmann rearrangement. 14,15-Anhydro-20-hydroxyecdysone (Z)-oxime under analogous conditions (reaction with p-toluenesulfonyl chloride in acetone in the presence of Na2CO3) gave rise to 20 ...
