The alpha- and beta-epoxides of 3beta-acetoxy-5alpha-lanost-9(11)-en-7-one.
The structures of 3beta-acetoxy-9alpha,11alpha-epoxy-5alpha-lanost-9(11)-en-7-one and 3beta-acetoxy-9beta,11beta-epoxy-5alpha-lanost-9(11)-en-7-one, C(32)H(52)O(4), 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-H...O interactions are present.
