A Novel Synthetic Approach from Diosgenin to a 17α‐Hydroxy Orthoester via a Regio‐ and Stereo‐Specific Rearrangement of an Epoxy Ester
摘要:
A cholesterol model compound, containing 16beta-acetoxy, 17alpha-hydroxy, and (20S, 22R)-epoxy groups was synthesized from diosgenin in 13 steps and was rearranged regio- and stereo-specifically to an orthoester with BF3.Et2O.
