Diisopropyl 3-[(E)-2-(3,4-dimethoxy-phen-yl)ethen-yl]-5-oxocyclo-hex-3-ene-1,1-dicarboxyl-ate.

ABSTRACT: The title compound, C(24)H(30)O(7), displays a trans configuration with respect to the C=C bond. The cyclo-hexenone ring has an envelope conformation; the flap atom (with the isopropoxycarbonyl groups) is displaced by 0.664?(3)?Å from the plane of the other five ring atoms and the carbonyl O atom. The dihedral angle between the cyclo-hexenone ring and the benzene ring is 7.85?(9)°. The meta and para meth-oxy O atoms are displaced by 0.003?(7) and 0.031?(4)?Å, respectively, from the benzene ring to which they are attached.

The title compound, C(24)H(30)O(7), displays a trans configuration with respect to the C=C bond. The cyclo-hexenone ring has an envelope conformation; the flap atom (with the isopropoxycarbonyl groups) is displaced by 0.664 (3) Å from the plane of the other five ring atoms and the carbonyl O atom. The dihedral angle between the cyclo-hexenone ring and the benzene ring is 7.85 (9)°. The meta and para meth-oxy O atoms are displaced by 0.003 (7) and 0.031 (4) Å, respectively, from the benzene ring ...[more]

Project description:In the title compound, C(26)H(22)Cl(2)O(4), the cyclo-hexenone ring adopts an approximate half-chair conformation, with two C atoms displaced by -0.485?(6) and 0.218?(6)?Å from the plane of the other four ring atoms.

(1RS,6SR)-Ethyl 4-(2,4-dichloro-phen-yl)-6-(4-fluoro-phen-yl)-2-oxocyclo-hex-3-ene-1-carboxyl-ate.

Project description:There are two symmetry-independent mol-ecules in the asymmetric unit of the title compound, C(21)H(17)Cl(2)FO(3). Both these mol-ecules are very similar: the normal probability plots for bond lengths, angles and even for torsion angles show that the differences are of a statistical nature. A pseudocentre of symmetry is located between the symmetry-independent mol-ecules at [0.245?(1), 0.535?(19), 0.909?(1)]. The cyclo-hexene rings have slightly distorted sofa conformations in both mol-ecules and the two benzene rings are inclined by dihedral angles of 61.33?(14) and 62.85?(14)°. In the crystal, relatively short inter-molecular C-H?O inter-actions join mol-ecules into homomolecular (i.e. ?AAA? and ?BBB?) chains along the b axis. These chains are inter-connected by further heteromolecular C-H?O inter-actions.

(1RS,6SR)-Ethyl 4-(4-chloro-phen-yl)-6-(4-fluoro-phen-yl)-2-oxocyclo-hex-3-ene-1-carboxyl-ate toluene hemisolvate.

Project description:In the crystal structure of the title compound, C(21)H(18)ClFO(3)·0.5C(7)H(8), the toluene solvent mol-ecules occupy special positions on centres of symmetry, and consequently are disordered across this site. The cyclo-hexene ring has a slightly distorted sofa conformation; the two benzene rings are inclined by 72.90?(7)° and their planes make dihedral angles of 30.09?(10) (chloro-phen-yl) and 88.13?(6)° (fluoro-phen-yl) with the approximately planar part of the cyclo-hexenone ring [maximum deviation from plane through five atoms is 0.030?(2)?Å, the sixth atom is 0.672?(3)Å out of this plane]. Weak inter-molecular C-H?O and C-H?X (X = F, Cl) inter-actions join mol-ecules into a three-dimensional structure. Also, a relatively short and directional C-Cl?F-C contact is observed [Cl?F = 3.119?(2)?Å, C-Cl?F = 157.5?(2)° and C-F?Cl 108.3?(2)°]. The solvent mol-ecules fill the voids in the crystal structure and are kept there by relatively short and directional C-H?? inter-actions.
