ABSTRACT: In the title compound, C(18)H(19)N(3)O(2), the dihedral angle between the benzene rings is 20.47?(10)° and an intra-molecular N-H?O hydrogen bond occurs, generating an S(5) ring. In the crystal, inversion dimers linked by pairs of N-H?O hydrogen bonds lead to R(2) (2)(8) loops.

Project description:In the title compound, C(17)H(16)N(2)O(2)S, the pyrazinone ring is non-planar (r.m.s. deviation = 0.1595?Å), with maximum deviations for the 4-position N atom and the adjacent non-fused-ring C atom of 0.2557?(15) and -0.2118?(16)?Å, respectively. The dihedral angle between the benzyl ring and pyrazinone rings is 30.45?(18)°. Inter-molecular N-H?O hydrogen-bonding inter-actions forms inversion dimers which lead to eight-membered R(2) (2)(8) ring motifs. The dimers are further connected by C-H?O inter-actions.

4,4'-[(2R*,3R*,4R*,5R*)-3,4-Dimethyl-tetra-hydro-furan-2,5-di-yl]diphenol.

Project description:The title mol-ecule, C(18)H(20)O(3), is a furan-oid lignan extracted from the leaves of Larrea tridentata. The relative absolute configuration for the four chiral centers was established, showing that this compound is 4-epi-larreatricin, which has been previously reported in the literature. The mol-ecule displays noncrystallographic C(2) symmetry, with the methyl and phenol substituents alternating above and below the mean plane of the furan ring. The conformation of this ring is described by the pseudorotation phase angle P = 171.3° and the maximum out-of-plane pucker ?(m) = 37.7°. These parameters indicate that the furan ring adopts the same conformation as the ribose residues in B-DNA. The packing is dominated by inter-molecular O-H?O hydrogen bonds. The phenol hy-droxy groups form chains in the [110] direction and these chains inter-act via O-H?O(furan) contacts.

Project description:In the title compound, C20H20N2O3, the central 2,5-di-hydro-1H-pyrrole ring [r.m.s. deviation = 0.014?(1)?Å] is oriented at dihedral angles of 77.81?(6) and 25.33?(6)°, respectively, to the attached phenyl ring and the aniline phenyl ring. An intra-molecular N-H?O hydrogen bond occurs. In the crystal, mol-ecules are linked through pairs of N-H?O hydrogen bonds, forming inversion dimers with an R 2 (2)(10) ring motif. Two weak C-H?? inter-actions are also observed.

Project description:The mol-ecule of the title compound, C42H32N6O, is built up from one pyrazole ring linked to three phenyl rings and to an approximately planar [maximum deviation = 0.0455?(15)?Å] quinoxaline system connected to a phenyl-benzohydrazide group.
