Cholest-5-ene.

Project description:The asymmetric unit of the title compound, C(27)H(46), contains two crytallographically independent cholest-5-ene mol-ecules (A and B). In each mol-ecule, the three six-membered rings are all in chair conformations, while the five-membered ring is in a twist conformation. The terminal isopropyl group of mol-ecule A has a (-)-gauche conformation, whereas that of mol-ecule B has a (+)-gauche conformation. No significant inter-molecular inter-actions are observed in the crystal structure.

3?-Chloro-N-methoxy-N-methyl-cholest-5-ene-24-carboxamide.

Project description:The title compound, C26H42ClNO2, is a 3?-chloro steroid with a Weinreb amide at the C-24 position. The two cyclo-hexane and the cyclo-hexene rings adopt chair and boat conformations, respectively. The cyclo-pentane ring has an envelope conformation.

A second monoclinic polymorph of 3?-chloro-cholest-5-ene.

Project description:The title compound, C(27)H(45)Cl, is a second monoclinic polymorph which crystallizes in the space group P2(1) with four crystallographically independent mol-ecules in the asymmetric unit. The structure was previously reported [Bernal et al. (1940 ?). Philos. Trans. R. Soc. London Ser. B, 239, 135-182; Vani & Vijayan (1979 ?). Mol. Cryst. Liq. Cryst.51, 253-264], also in the space group P2(1), but with two unique mol-ecules in the asymmetric unit. As in the previously reported structures, rings A and C in the mol-ecule adopt chair conformations with half-chair conformations for rings B and D. The ring junctions B-C and C-D are trans, whereas the junction A-B is quasi-trans. In the crystal structure, mol-ecules are arranged in a head-to-tail fashion along a and are stacked along the b axis.

Westphalen's diol diacetate: 19(10→5)-abeo-5β-cholest-9-ene-3β,6β-diyl diacetate.

Project description:THE STRUCTURE OF THE TITLE STEROID [ALTERNATIVE NAME: 3β,6β-diacet-oxy-5β-methyl-19-norcholest-9(10)-ene], C31H50O4, confirms the generally accepted mechanism for the rearrangement of a cholestan-5α-ol derivative reported a century ago by Westphalen. The methyl group at position 10 of the starting material migrates to position 5 in the steroidal nucleus, while a Δ(9) bond is formed, as indicated by the C=C bond length of 1.347 (4) Å. The methyl transposition leaves the 5R configuration unchanged, with the methyl oriented towards the β face. During the rearrangement, the steroidal B ring experiences a conformational distortion from chair to envelope with the C atom at position 6 as the flap. In the title structure, the isopropyl group of the side chain is disordered over two positions, with occupancies of 0.733 (10) and 0.267 (10). The carbonyl O atom in the acetyl group at C3 is also disordered with an occupancy ratio of 0.62 (4):0.38 (4).

The isolation of cholest-5-ene-3beta,26-diol from human brain.

Project description:Cholest-5-ene-3beta,26-diol, isolated from human brain, was further characterized by oxidation to 3-oxocholest-4-en-26-ol and to 3-oxocholest-4-en-26-oic acid. Identification was achieved by comparison (by t.l.c., g.l.c. and g.l.c.-mass spectrometry) with corresponding reference compounds derived from kryptogenin.

1,1'-[(5-Hy-droxy-methyl-1,3-phenyl-ene)bis-(methyl-ene)]dipyridin-4(1H)-one monohydrate.

Project description:The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68?(8) and 83.65?(8)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71?(10)° with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H?O hydrogen-bonding inter-actions and while the water mol-ecules form a C(2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy-droxy groups are engaged in O-H?O=C hydrogen bonds described by a C(1) (1)(12) graph-set motif which runs parallel to the a axis.

1,2-Bis[bis-(methyl-sulfan-yl)methyl-ene]hydrazine.

Project description:The title compound, C(6)H(12)N(2)S(4), was obtained as a by-product (8%) during the reaction of the electrogenerated cyano-methyl anion with phenyl-amine, carbon disulfide and methyl iodide. The mol-ecule, with the exception of 8 H atoms, lies on a crystallographic mirror plane and is arranged around an inversion centre located at the mid-point of the N-N bond.

N'-[(5-Methyl-furan-2-yl)methyl-ene]isonicotinohydrazide.

Project description:The title compound, C(12)H(11)N(3)O(2), was prepared by the reaction of isonicotinohydrazide and 5-methyl-furan-2-carbalde-hyde. The pyridine ring makes a dihedral angle of 46.90 (9)° with the mean plane of the furan ring. The crystal packing is stabilized by a bifurcated inter-molecular N-H⋯(N,O) inter-action.

1,4-Phenyl-enebis(methyl-ene) dicarbamate.

Project description:The title compound, C(10)H(12)N(2)O(4), is a phenyl dicarbamate with crystallographically imposed inversion symmetry. The dihedral angle between the carbamo-yloxy plane [i.e. the plane of the N-C(O)-O fragment; r.m.s. deviation = 0.002?(3)?Å] and the plane of the aryl ring is 29.2?(1)°. In the crystal, two different centrosymmetric N-H?O hydrogen-bond inter-actions are observed; these are described as R(2) (2)(8) and R(2) (4)(8) in graph-set notation. The rings form an alternating sequence, linking the mol-ecules into a sheet structure parallel to (011).
