N,N'-Bis(3?-acet-oxy-5?-cholest-6-yl-idene)hydrazine.

ABSTRACT: 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?(4):0.060?(4) and 0.791?(7):0.209?(7), respectively. In the crystal, mol-ecules are stacked along the a axis through van der Waals inter-actions.

3β,6α-Diacet-oxy-5,9α-dihy-droxy-5α-cholest-7-en-11-one.

Project description:The title compound, C31H48O7, a polyoxygenated steroid, was obtained by chemical oxidation of 7-de-hydro-cholesteryl acetate. The mol-ecular geometry features trans A/B and C/D junctions at the steroid core with the acetyl groups in the equatorial position and a fully extended conformation for the alkyl side chain. A chair conformation is observed for rings A and C while ring B adopts a half-chair conformation. The five-membered ring D has an envelope conformation, with the C atom bearing the methyl group at the flap. The terminal isopropyl group and one acetyl group are disordered over two sets of sites with 0.774 (8):0.226 (8) and 0.843 (7):0.157 (7) ratios, respectively. An intra-molecular S(6) O-H⋯O hydrogen-bonding motif involving a hy-droxy donor and acceptor is observed. In the crystal, chains of mol-ecules running along the b axis are formed via O-H⋯O hydrogen bonds between hy-droxy donors and carbonyl acceptors of the ordered acetyl group, giving rise to a C(14) motif. The chains are wrapped around the 21 screw axes.

16α-Bromo-17β-hydr-oxy-5α-androstan-3β-yl acetate.

Project description:The title compound, C(21)H(33)BrO(3), an inter-mediate in the synthesis of the neuromuscular blocking agent rocuronium bromide, contains two independent mol-ecules in the asymmetric unit, which have almost identical geometries: in both mol-ecules, the steroidal rings A, B and C have slightly flattened chair conformations and ring D assumes a half-chair conformation. In the crystal, O-H⋯O hydrogen bonds and weak C-H⋯O and C-H⋯Br inter-actions help to establish the packing.

6β-Chloro-5α-hydr-oxy-20-oxopregnan-3β-yl acetate.

Project description:The title steroid, C(23)H(35)ClO(4), is a pregnane derivative prepared by ring opening of the corresponding 5α,6α-ep-oxy steroid with BiCl(3). There are two symmetry-independent mol-ecules in the asymmetric unit that show no significant differences concerning bond lengths and angles. The conformation of the six-membered rings in both mol-ecules is close to a chair form, while the five-membered ring adopts an envelope conformation. All rings in both mol-ecules are trans-fused. The mol-ecules are held together by an extensive O-H⋯O hydrogen-bonding network.

3β,6β-Diacet-oxy-5,9α-dihy-droxy-5α-cholest-7-en-11-one acetic acid 0.04-solvate.

Project description:The title compound, C31H48O7·0.04CH3COOH, is a polyoxy-genated steroid obtained by selective chemical oxidation of 7-de-hydro-cholesteryl acetate. The asymmetric unit comprises three mol-ecules of the steroid (Z' = 3) and a mol-ecule of acetic acid which has occupancy factor 0.131 (5). The geometric parameters of the independent mol-ecules do not reveal significant differences. In one mol-ecule, the terminal isopropyl group is disordered over two sets of sites with occupancy ratio 0.869 (5):0.131 (5). The three mol-ecules reveal different hydrogen-bonding patterns. Each of them is involved in an intra-molecular S(6) hydrogen-bonding motif, involving hy-droxy groups as donor and acceptor. In the crystal, two independent mol-ecules form dimers through hydrogen bonding between an OH donor and an acetate carbonyl acceptor, giving rise to R 2 (2)(16) ring patterns. A single hydrogen bond between the OH group and a ketone carbonyl group is observed between two symmetry-independent mol-ecules.

Cholest-5-en-3β-yl 3-(4-eth-oxy-phen-yl)prop-2-enoate.

Project description: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 form. The two symmetry-independent mol-ecules pack in the crystal into separate layers parallel to (-102) with their long axis parallel to the [201] direction. Short inter-molecular C-H⋯O and C-H⋯π contacts are observed.

1,2-Bis(3-phen-oxy-benzyl-idene)hydrazine.

Project description:Mol-ecules of the title compound, C(26)H(20)N(2)O(2), reside on crystallographic centres of inversion located at the mid-point of the N-N bond. The benzyl-idene ring is essentially coplanar with the central hydrazine group, with an inter-planar angle of 4.5?(2)°, whereas the phenyl ring is oriented at 34.0?(3)° with respect to the mean plane of the central 1,2-dibenzyl-idenehydrazine group. In the crystal, C-H??(arene)-ring inter-actions link mol-ecules about inversion centres.

(E,E)-1,2-Bis[3-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The mol-ecule of the title compound, C(20)H(16)N(2)O(2), is centrosymmetric, the inversion center being located at the mid-point of the central azine bond. The conformation around the C=N bond is E. The whole mol-ecule (except for the H atoms) is essentially planar, with an r.m.s. deviation of 0.07 Å. In the crystal, mol-ecules are linked head-to-tail by pairs of C-H⋯O hydrogen bonds, forming inversion dimers, and resulting in the formation of chains propagating along [011].

(E,E)-1,2-Bis[4-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The mol-ecule of the title compound, C(20)H(16)N(2)O(2), is centrosymmetric with the mid-point of the central N-N bond located on an inversion center. The configuration around the C=N bond is E. The whole mol-ecule (except for the H atoms) is approximately planar, with an r.m.s. deviation of 0.07 Å. In the crystal, the presence of weak inter-molecular C-H⋯O hydrogen bonding involving each acetyl-ene H atom and the adjacent phen-oxy O atom results in the formation of supra-molecular chains.

(E,E)-1,2-Bis[3-meth-oxy-4-(prop-2-yn-1-yl-oxy)benzyl-idene]hydrazine.

Project description:The complete mol-ecule in the title compound, C(22)H(20)N(2)O(4), is generated by the application of an inversion centre. With the exception of the terminal acetyl-ene groups [C-O-C-C = -78.02?(17)°], the remaining atoms constituting the mol-ecule are essentially coplanar. The configuration around the C=N bond [1.282?(2)?Å] is E. The formation of supra-molecular chains mediated by C-H?O inter-actions, occurring between methyl-ene H and meth-oxy O atoms, is the most notable feature of the crystal packing.

Project description:The title mol-ecule, C(6)H(4)N(2)S(4), has a crystallographically imposed centre of symmetry located at the mid-point of the N-N single bond. The mol-ecule is essentially planar: the two five-membered rings form a dihedral angle of 0.17 (6)°. The crystal packing exhibits short inter-molecular S⋯S contacts of 3.549 (2) Å.
