Abstract
The title compound, C25H36O5, has two independent molecules in the asymmetric unit with similar geometry. The main difference between the two molecules relates to the conformation of the 17β-methyl ketone and 3β-acetoxy groups, the latter being disordered in one of the molecules. The five-membered ring adopts an unusual 13β-envelope conformation.
