Abstract:The title compound, alternatively called 24-nor-5-chol-22-ene-3,7α,12α-triyl triformate, C26H38O6, has a cis junction between two of the six-membered rings. All three of the six-membered rings have chair conformations that are slightly flattened and the five-membered ring has a 13,14α-half-chair conformation. The 3, 7α and 12α ring substituents are axial and the 17 group is equatorial. The 3-formyloxy group is involved in one weak intermolecular C—H…O bond, which links the molecules into dimers in a head-to-head fashion.
