Synthesis of 20-hydroxyecdysone oxime, its diacetonide, and their 14,15-anhydro derivatives
摘要:
20-Hydroxyecdysone oxime, its diacetonide, and the corresponding 14,15-anhydro derivatives were synthesized. Conditions were found for the preparation of the Z- and E-oximes, and their characteristic H-1 and C-13 NMR parameters were determined.
