3?-Acet-oxy-5?-cholestan-6-one 2-cyano-acetyl-hydrazone.

ABSTRACT: The asymmetric unit of the title compound, C(32)H(51)N(3)O(3), consists of two crystallographically independent mol-ecules, A and B; the 2-methyl-pentane group of mol-ecule A and the propane group of mol-ecule B are each disordered over two sets of sites, with refined site-occupancies of 0.825?(5):0.175?(5) and 0.630?(18):0.370?(18), respectively. In both mol-ecules, the three cyclo-hexane rings in the steroid fused ring systems adopt chair conformations while the cyclo-pentane rings adopt envelope and twist conformations in mol-ecules A and B, respectively. In the crystal, N-H?O and C-H?O hydrogen bonds link the two independent mol-ecules together, generating R(2) (1)(7) and R(2) (2)(8) ring motifs.
