Cholest-5-en-3β-yl N-phenylcarbamate
In the title compound, C(34)H(51)NO(2), the dihedral angle between the planes of the phenyl ring and the carbonyl group is 9.30 (2)°. No significant inter-molecular inter-actions are observed in the crystal structure. The C(5)H(11) fragment is disordered over two positions with site occupancies of 0.611 (6) and 0.389 (6).

In the title compound, C(21)H(30)N(2)O, there are five fused rings. The A and C rings adopt chair conformations, ring B adopts an 8β,9α-half-chair conformation and ring D adopts a 14α-envelope conformation. The pyrazole ring is planar. Inter-molecular O-H⋯N hydrogen bonds [H⋯N = 1.88 (5) Å] help to stabilize the crystal structure. The absolute structure was deduced from those of the starting ma...

In the crystal structure of the title compound, C(6)H(16)N(+)·C(34)H(52)O(2)PS(2) (-) or [(CH(3)CH(2))(3)NH](+)·[C(34)H(52)O(2)PS(2)](-), the cation and anion are paired via weak, inter-molecular, bifurcated N-H⋯(S,S) hydrogen bonds. The cholesteryl units form an alternating (herringbone) motif as well as an infinitely stacked layered structure along the b axis. The P-S bond lengths [1.975 (2) ...

In the asymmetric unit of the title compound, C(38)H(56)O(3), there are two symmetry-independent mol-ecules that differ in the rotation angle along the C-O bond between the 3-(4-eth-oxy-phen-yl)prop-2-enoate and cholest-5-en-3β-yl groups by 169.3 (3)°. In both mol-ecules, steroid ring B adopts a half-chair conformation, rings A and C adopt a chair conformation and ring D exists in an envelope f...
