- The absolute stereochemistry of a diterpene from Ballota aucheri
-
The semi-synthetic transformation of hispanolone, isolated from Ballota africana, into βp-hydroxy-15,16-epoxylabda-8,13(16),14-trien-7-one has established an ent-labdane absolute stereochemistry for a diterpene metabolite originally isolated from B. aucheri.
