Transformation of ω-anhydro-20-hydroxyecdysone diacetonide into 7,8α-dihydroponasterone a and its acetonides
摘要:
7,8 alpha-Dihydroponasterone A and its mono- and diacetonides were synthesized via catalytic hydrogenation of omega-anhydro-20-hydroxyecdysone 2,3: 20,22-diacetonide over Pd/C in methanol in the presence of sodium methoxide.
