Description:
In the title compound, C19H28O3, the ester linkage in ringAis equatorial. The six-membered ringsAandBhave chair conformations, but ringCcan be better described as a half-chair. The five-membered ringDadopts a 14α-envelope conformation. TheA/B,B/CandC/Dring junctions are alltrans. The packing of the molecules is assumed to be dictated mainly by intermolecular hydrogen bonds. There is an intramolecular C—H...O interaction between the O11 atom of the epoxy group and the methyl C18 group.
