3β-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...
متن کامل3β,5α,6β-Trihydroxyandrostan-17-one
The title compound, C(19)H(30)O(4), is an androstan-17-one derivative synthesized from the dehydro-epiandrosterone through a sequential addition of an oxidant, followed by a trans-diaxial opening of the epoxide generated, with Bi(OTf)(3) (OTf is trifluoro-methane-sulfonate). The six-membered rings have a slightly flattened chair conformation, while the five-membered ring adopts a 14-α envelope ...
متن کامل(22E,24R)-3β,5α,9α-Trihydroxyergosta-7,22-dien-6-one monohydrate
The title ergosterol compound, C(28)H(44)O(4)·H(2)O, is composed of four fused rings (three six-membered and one five-membered) and a side chain. It is a derivative of ergosterol and was isolated from a marine-derived halotolerant fungus, Cladosporium cladosporioides PXP-49. In the crystal, mol-ecules are assembled by classical O-H⋯O hydrogen bonds, forming a two-dimensional network, with base ...
متن کاملN,N′-Bis(3β-acetoxy-5α-cholest-6-ylidene)hydrazine
The asymmetric unit of the title compound, C(58)H(96)N(2)O(4), contains two crystallographically independent mol-ecules. All cyclohexane rings are in chair conformations, while the furan ring is in an envelope conformation in one mol-ecule and a twist conformation in the other. Two acetaldehyde and one isobutane groups are disordered over two orientations with refined site occupancies of 0.940 ...
