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 Β°, Z ---2). IV was previously shown to be an important intermediate in the acid-catalyzed iso
