3α,4α-Epoxy-5α-androstan-17β-yl acetate
The title compound, C(21)H(32)O(3), results from modifications of the A and D rings of the aromatase substrate androstenedione. Ring A adopts a conformation between 10β-sofa and 1α,10β half-chair. Rings B and C are in slightly flattened chair conformations. Ring D approaches a 13β-envelope conformation, probably due to the acet-oxy substituent, and shows a very short Csp(3)-Csp(3) bond next to ...
متن کامل3β-Chloro-5α-cholestan-6-one
The asymmetric unit of the title compound, C(27)H(45)ClO, consists of two crystallographically independent mol-ecules. In both mol-ecules, the three cyclo-hexane rings in the steroid fused-ring systems adopt chair conformations, while the cyclo-pentane ring adopts a half-chair conformation in one mol-ecule and an envelope conformation in the other. In the crystal, the mol-ecules are linked into...
متن کامل3β-Acetoxy-5α-cholestan-6-one 2-cyanoacetylhydrazone
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 ring...
