(22E,24R)-3?,5-Cyclo-5?-ergosta-22-en-6-one.

ABSTRACT: In the title mol-ecule, C(28)H(44)O, the two six-membered rings have a chair conformation and the two five-membered rings haveenvelope conformations. The crystal packing exhibits no short inter-molecular contacts. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of the title compound.

3-(4-Bromo-phen-yl)cyclo-pent-2-en-1-one.

Project description:In the title compound, C11H9BrO, the cyclo-pentenone ring is almost planar with an r.m.s. deviation of 0.0097?Å. The largest inter-ring torsion angles [2.4?(3), 1.3?(3) and 3.53?(2)°] reveal only a very small twist between the rings, and suggest that the two rings are conjugated. The mol-ecule is slightly bowed, as shown by the small dihedral angle between the rings [5.3?(1)°]. The crystal packing pattern consists of parallel sheets that stack parallel to the ac plane. Each sheet consists of mol-ecules that pack side-to-side with the same relative orientation of phenyl and cyclo-pentenone rings along the a- and c-axis directions. Slipped side-to-side, face-to-face and edge-to-face inter-actions exist between pairs of sheets with edge-to-edge and edge-to-face O?H-C(sp (2)) weak hydrogen-bond contacts. A relatively short edge-to-face contact (2.77?Å) also exists between pairs of sheets.

3-(4-Chloro-anilino)-5,5-dimethyl-cyclo-hex-2-en-1-one.

Project description:The asymmetric unit of the title compound, C(14)H(16)ClNO, contains two independent mol-ecules, both with the cyclo-hexene ring in a sofa conformation. In the crystal, N-H?O hydrogen bonds link the mol-ecules related by translation along the a axis into two crystallographically independent chains. Weak C-H?? inter-actions are also observed.

3-(4-Chloro-anilino)-2,5-dimethyl-cyclo-hex-2-en-1-one.

Project description:In the title compound, C(14)H(16)ClNO, the dihedral angle between the benzene ring and the conjugated part of the cyclo-hexene ring is 61.7?(2)°. Part of the cyclo-hexene ring and one of the attached methyl groups are disordered over two orientations with occupancies of 0.602?(7) and 0.398?(7). In addition, the crystal studied was a racemic twin [Flack parameter = 0.58?(4)]. In the crystal, the mol-ecules are linked into chains in the b-axis direction by inter-molecular N-H?O hydrogen bonds. C-H?O and C-H?Cl inter-actions are also observed.

(5R)-5-[(1R)-2,2-Dichloro-1-methyl-cyclo-prop-yl]-2-methyl-cyclo-hex-2-en-1-one.

Project description:The title compound, C(11)H(14)Cl(2)O, was synthesized by the reaction of a dichloro-methane solution of (R)-carvone and potassium tert-butano-late in the presence of a catalytic amount of benzyl-triethyl-ammonium chloride in chloro-form. The cyclo-hexene ring adopts a half-boat conformation. The cyclo-propyl ring is unsymmetrical, the shortest C-C bond being distal to the alkyl-substituted C atom. The crystal packing is stabilized only by van der Waals inter-actions.

Project description:In the title compound, C(19)H(18)O, the cyclo-hexene ring has an envelope conformation with the methine C atom on the flap. The phenyl and methyl-phenyl rings form a dihedral angle of 85.93?(11)°. The crystal packing is consolidated by van der Waals forces and weak C-H?? inter-actions.

Project description:The title compound, C(10)H(11)Cl(5)O, is a chiral mol-ecule with two stereogenic centres. However, it crystallizes as a racemate. One of enanti-omers reveals the relative configuration (2S*,5R*). The cyclo-hexene ring adopts a half-chair conformation.

3-(4-Chloro-benzene-sulfonamido)-5-methyl-cyclo-hex-2-en-1-one.

Project description:For the title compound, C(13)H(14)ClNO(3)S, geometrical parameters, determined using X-ray diffraction techniques, are compared with those calculated by density functional theory (DFT), using hybrid exchange-correlation functional, B3LYP methods. The dihedral angle between the benzene ring and the conjugated part of the cyclo-hexene ring is 87.47?(5)°. The cyclo-hexene ring and its substituents are disordered over two conformations, with occupancies of 0.786?(3) and 0.214?(3). In the crystal, mol-ecules are linked into chains in the c-axis direction by inter-molecular N-H?O(C=O) hydrogen bonds. C-H?O inter-actions are also observed.

(2E,6E)-2,6-Bis(4-methyl-benzyl-idene)cyclo-hex-3-en-1-one.

Project description:The title compound, C(22)H(20)O, shows an approximately planar cyclo-hexenone ring [maximum deviation = 0.069?(4)?Å], with a disordered position of the C=C bond [ratio = 0.71?(2)/0.29?(2)]. The benzene rings of the 4-methyl-benzyl-idene units, attached in the 2- and 6-positions to the cyclo-hexenone ring, are rotated in the same direction by 28.6?(4) and 22.4?(4)°, with respect to the mean plane of the cyclo-hexenone ring [fraction 0.71?(2); maximum deviation = 0.06?(3)?Å]. In the crystal, mol-ecules are packed in the manner of a distorted hexa-gonal rod packing with their long axes all aligned along [201]. A number of C-H?? inter-actions stablize the crystal structure.

2-[(4-Chloro-phen-yl)(2-hy-droxy-5-oxo-cyclo-pent-1-en-1-yl)meth-yl]-3-hy-droxy-cyclo-pent-2-en-1-one.

Project description:There are two mol-ecules in the asymmetric unit of the title compound, C(17)H(15)ClO(4), in which the dihedral angles between the five-membered rings are 57.3?(1) and 51.4?(1)°. An intra-molecular O-H?O hydrogen bond occurs in each mol-ecule. In the crystal, O-H?O and C-H?O hydrogen bonds link the moleclues into chains along the b axis.

(E)-3-Hy-droxy-5,5-dimethyl-2-(3-phenyl-prop-2-en-1-yl)cyclo-hex-2-en-1-one.

Project description:Five of the atoms of the six-membered cyclo-hexene ring of the title compound, C(17)H(20)O(2), are essentially coplanar (r.m.s. deviation = 0.006?Å), with the sixth (the dimethyl-methyl C atom) deviating from the mean plane of the five atoms by 0.610?(2)?Å. This plane is nearly perpendicular to the cinnamyl portion, the two planes being aligned at 85.1?(1)°. Two mol-ecules are linked by an O-H?O hydrogen bond about a center of inversion. The cyclo-hexene ring is disordered over two directly overlapping positions. As a result, the hy-droxy group and the keto O atom cannot be distinguished from one another.
