In the title compound, C 29 H 50 O 4 , the six-membered rings adopt slightly flattened chair conformations. The fivemembered ring has an envelope conformation. The molecules are linked into chains running along the b axis by O-HÁ Á ÁO hydrogen bonds.
The X-ray crystal structure of 3~-benzoyloxy-6a-chloro-5a-cholest-7-ene (IV) was determined by the heavy atom method and ref'med to R ---0.063 (space group P2s, a --11.364, b = 11.089, c --12.232,/~ = 99.43 °, Z ---2). IV was previously shown to be an important intermediate in the acid-catalyzed iso
