E-[4-(β-d-Allopyranosyloxy)phenyl]-1-(4-chlorophenyl)prop-2-enone ethanol solvate
The title compound, C(21)H(21)ClO(7)·C(2)H(5)OH was synthesized by the condensation reaction between helicid [systematic name: 4-(β-d-allopyranos-yloxy)benzaldehyde] and 4-chloro-aceto-phen-one in ethanol. In the mol-ecular structure, the pyran-oside ring adopts a chair conformation. In the crystal structure, the molecules are linked by inter-molecular O-H⋯O hydrogen bonds involving the OH grou...

The title compound, C(21)H(21)BrO(7)·C(2)H(6)O, was synthesized by the Claisen-Schimidt reaction of helicid (systematic name: 4-formyl-phenyl-β-d-allopyran-oside) with 4-bromo-aceto-phenone in ethanol. The pyran ring adopts a chair conformation. In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular O-H⋯O hydrogen bonds.

In the title compound, C(17)H(15)Cl(2)NO, the dimethyl-amino-phenyl group is close to coplanar with the central propenone group [dihedral angle = 13.1 (1)° between the mean planes], while the dichloro-phenyl group is twisted from the plane [dihedral angle = 64.0 (1)°]. In the crystal, C-H⋯O and weak C-H⋯π inter-actions are formed between mol-ecules.

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-molecu...
