摘要

Autoxidation of (11S)-12-hydroxy-7α-eudesmane-3, 6-dione in the presence of p- toluenesulfonic acid gave 6, 12-epoxy-11β-eudesma-4, 6-dien-3-one, which was oxidized with m-chloroperoxybenzoic acid to give (11R)-7α, 12-dihydroxyeudesm-4-ene-3, 6-dione. Transformation of some other 12-hydroxyeudesman-6-ones into 7, 12-dihydroxyeudesman- 6-ones was also examined.
