(E)-Methyl 3-(3,4-dihy-droxy-phen-yl)acrylate.

ABSTRACT: The benzene ring in the title compound, C(10)H(10)O(4), makes an angle of 4.4?(1)° with the C-C-C-O linker. The hy-droxy groups are involved in both intra- and inter-molecular O-H?O hydrogen bonds. The crystal packing is stabilized by O-H?O hydrogen-bonding inter-actions. The mol-ecules of the caffeic acid ester form a dimeric structure in a head-to-head manner along the a axis through O-H?O hydrogen bonds. The dimers inter-act with one another through O-H?O hydrogen bonds, forming supermolecular chains. These chains are further extended through C-H?O hydrogen bonds as well as van der Waals inter-actions into the final three-dimensional architecture.

The benzene ring in the title compound, C(10)H(10)O(4), makes an angle of 4.4 (1)° with the C-C-C-O linker. The hy-droxy groups are involved in both intra- and inter-molecular O-H⋯O hydrogen bonds. The crystal packing is stabilized by O-H⋯O hydrogen-bonding inter-actions. The mol-ecules of the caffeic acid ester form a dimeric structure in a head-to-head manner along the a axis through O-H⋯O hydrogen bonds. The dimers inter-act with one another through O-H⋯O hydrogen bonds, forming supermolecula ...[more]

Project description:The racemic title compound, C(12)H(16)O(6)S, possesses a five-membered ring that adopts an envelope-shaped conformation; the two hy-droxy groups occupy quasi-axial positions. Adjacent mol-ecules are linked by O-H?O hydrogen bonds to generate a ribbon that runs along the a axis of the ortho-rhom-bic unit cell. The crystal studied was an inversion twin.

(E)-N-Butyl-3-(3,4-dihy-droxy-phen-yl)acryl-amide hemihydrate.

Project description:In the title compound, C(13)H(17)NO(3)·0.5H(2)O, a new caffeic acid amide derivative, the solvent water mol-ecule lies on a twofold axis and the terminal ethyl group appears disordered with occupancy factors of 0.525?(6) and 0.475?(6). The benzene ring makes an angle of 17.3?(2)° with the C=C-C-O linker. The presence of an ethyl-enic spacer in the caffeic acid amide mol-ecule allows the formation of a conjugated system, strongly stabilized through ?-electron delocalization. The C=C double bond in the linker is trans, similar to those previously reported in caffeic esters. The crystal is stabilized by O-H?O, N-H?O and C-H?O hydrogen bonds. The mol-ecules of the caffeic acid amide form a supermolecular planar structure through O-H?O hydrogen bonds between a hy-droxy group of one caffeic acid mol-ecule and a carbonyl O atom of another. These planes inter-act via C-H?O, O-H?O and N-H?O hydrogen bonds to form a three-dimensional network.

Crystal structure of 1-(2,4-dihy-droxy-6-methyl-phen-yl)ethanone.

Project description:The title compound, C9H10O3, is a bioactive secondary metabolite, isolated from the endophytic fungus Nodulisporium sp. The compound exhibits an intra-molecular O-H⋯O hydrogen bond between the phenolic H atom and the carbonyl O atom of the adjacent acetyl group. In the crystal, mol-ecules are linked by hydrogen bonds involving the 4-phenolic H atom and a symmetry-related carbonyl O atom of a neighboring mol-ecule, resulting in extended supra-molecular chains along the a-axis direction. Aromatic π-π stacking inter-actions between the nearly parallel benzene rings of adjacent chains [centroid-centroid distance = 3.7478 (8) Å] further stabilize the three-dimensional supra-molecular framework.

(E)-Methyl 3-(3,4-dimeth-oxy-phen-yl)-2-[(1,3-dioxoisoindolin-2-yl)meth-yl]acrylate.

Project description:In the title compound, C(21)H(19)NO(6), the isoindole ring system is essentially planar [maximum deviation = 0.019?(2)?Å for the N atom] and is oriented at a dihedral angle of 51.3?(1)° with respect to the benzene ring. The two meth-oxy groups are almost coplanar with the attached benzene ring [C-O-C-C = 3.7?(4) and 4.3?(4)°]. The mol-ecular conformation is stabilized by an intra-molecular C-H?O hydrogen bond, which generates an S(9) ring motif. In the crystal, mol-ecules are linked through bifurcated C-H?(O,O) hydrogen bonds having R(1) (2)(5) ring motifs, forming chains along the b-axis direction. The crystal packing is further stabilzed by ?-? inter-actions [centriod-centroid distance = 3.463?(1)?Å].
