Abstract: The structure of bharangin triacetate [systematic name: 6,10-bis(acetyloxy)-8-isopropyl-4,4,11a-trimethyl-2-oxo-2,3,4,6,11,11a-hexahydrobenzo[5,6]cyclohepta[1,2-b]pyran-9-yl acetate], C₂₆H₃₂O₈, a tricyclic diterpenoid, contains a seven-membered cycloheptadiene ring forming two planar parts, a six-membered -lactone ring in a boat conformation and a planar benzene ring. The structure is stabilized by intra- and intermolecular C-HO interactions.
