Deskripsi

The title compound, C31H44O5, was synthesized from isosteviol (systematic name: ent-16-ketobeyeran-19-oic acid). In the molecule, the three six-membered rings adopt chair conformations and the stereochemistry of the A/B and B/C ring junctions are trans. The five-membered ring D adopts an envelope conformation with the methylene C atom as the flap.
