(E)-1-(4-Chloro-phen-yl)-3-[4-(2,3,4,6-tetra-O-acetyl-?-d-allopyranos-yloxy)phen-yl]prop-2-en-1-one.

ABSTRACT: The asymmetric unit of the title compound, C(29)H(29)ClO(11), contains two independent mol-ecules of similar geometry, both adopting an E conformation about the C=C double bond. The dihedral angles formed by benzene rings are 10.73?(16) and 13.79?(18)°. The pyran-oside rings adopt a chair conformation. Intra-molecular C-H?O close contacts occur. The crystal packing is stabilized by inter-molecular C-H?O hydrogen bonds.

(2E)-1-(3-Chloro-phen-yl)-3-(4-chloro-phen-yl)prop-2-en-1-one.

Project description:The title compound, C(15)H(10)Cl(2)O, is a chalcone with 3-chloro-phenyl and 4-chloro-phenyl substituents bonded at the opposite ends of a propenone group, the biologically active region. The dihedral angle between mean planes of these two chloro-substituted benzene rings is 46.7?(7)° compared to 46.0?(1) and 32.4?(1)° in similar published sructures. The angles between the mean plane of the prop-2-en-1-one group and the mean planes of the 3-chloro-phenyl and 4-chloro-phenyl rings are 24.1?(2) and 29.63°, respectively. While no classical hydrogen bonds are present, weak inter-molecular C-H??-ring inter-actions are observed, which contribute to the stability of crystal packing.

(E)-3-[4-(Hex-yloxy)phen-yl]-1-(2-hydroxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(21)H(24)O(3), the conformation of the enone group is s-cis. The benzene rings are inclined at an angle of 7.9?(1)°. The alk-oxy tail is planar, with a maximum deviation from the least-squares plane of 0.009?(2)?Å, and adopts a trans conformation throughout. An intra-molecular O-H?O inter-action between the keto and hydr-oxy groups forms S(6) ring motifs. In the crystal, mol-ecules are arranged in a head-to-tail manner down the a axis and are subsequently stacked along the b axis, forming mol-ecular sheets parallel to the ab plane. The crystal structure is further stabilized by weak C-H?? inter-actions and short C?O [3.376?(2)?Å] contacts.

(E)-3-[4-(Dodec-yloxy)phen-yl]-1-(2-hydroxy-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(27)H(36)O(3), the asymmetric unit consists of two crystallographically independent mol-ecules. The aromatic rings form dihedral angles of 17.1 (2) and 17.6 (2)° in the two molecules. In both mol-ecules, the enone groups adopt an s-cis conformation and the alkoxyl chains are in trans conformations curving out of the zigzag plane. Intra-molecular O-H⋯O hydrogen bonds involving the keto and hydr-oxy groups generate S(6) ring motifs. The mol-ecules are stacked alternately in a head-to-tail fashion along the a axis and the crystal structure is stabilized by weak C-H⋯π inter-actions. The crystal studied was a non-merohedral twin, the ratio of components being 0.788 (2):0.212 (2).

Project description:In the title compound, C(22)H(18)O(3), an intra-molecular O-H?O hydrogen bond stabilizes the mol-ecular structure, forming an S(6) ring motif.
