The structures of 3β-acetoxy-9α,11α-epoxy-5α-lanost-9(11)-en-7-one and 3β-acetoxy-9β,11β-epoxy-5α-lanost-9(11)-en-7-one, C32H52O4, differ in their respective substituted cyclohexanone rings but adopt similar conformations in the other three rings. In both of the crystal structures, weak intermolecular C—HO interactions are present.
