Odinokov,Galyautdinov,Nedopekin,Ves'kina,Khalilov

, p. 952 - 956 (2003)

Hydrogenation of 20-hydroxyecdysone 2,3:20,22-diacetonide and 20,22-acetonide over palladium catalyst yields podecdysone B 20,22-acetonide. Acid hydrolysis of the latter affords podecdysone B which is a natural phytoecdysteroid.
