Project description:In the title compound, C(25)H(32)O(7), the 3-hy-droxy-5,5-dimethyl-cyclo-hex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intra-molecular hy-droxy-ketone O-H⋯O inter-action between the two substituted cyclo-hexane rings as well as a short intra-molecular phenol-meth-oxy O-H⋯O inter-action.

2-[(2-Chloro-phen-yl)(hy-droxy)meth-yl]phenol.

Project description:In the title compound, C13H11ClO2, the dihedral angle between the mean planes of the 2-chloro-phenyl and phenol rings is 87.4 (9)°. The methyl hy-droxy group lies nearly perpendicular to the plane of its attached benzene ring [O-C-C-C torsion angle = 84.3 (3)°]. The two hy-droxy groups lie on the same side of the mol-ecule and are in a slightly twisted gauche conformation [O-C-C-O torsion angle = 77.1 (8)°] to each other. In the crystal, O-H⋯O hydrogen bonds between nearby methyl-hydroxy groups form dimers in alternating pairs aligned diagonally along the b axis. A view along the c axis reveals a hexa-meric aggregate mediated by a ring of six O-H⋯O hydrogen bonds generating an R 6 (6)(12) motif loop.

Project description:In the title compound, C21H23N3O7, the pyrimidine-dione ring adopts a screw-boat conformation, whereas the cyclo-hexenone ring adopts an envelope conformation, with the C atom bearing the methyl groups as the flap atom. The dihedral angle between the mean planes of the pyrimidine-dione and cyclo-hexenone rings is 58.78?(2)°. The pyrimidine-dione and cyclo-hexenone rings form dihedral angles of 59.94?(3) and 54.73?(2)°, respectively, with the 4-nitro-phenyl ring. Relatively strong intra-molecular O-H?O hydrogen bonds are observed. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds, forming a chain along the c-axis direction.

3-Hy-droxy-2-[(2-hy-droxy-4,4-dimethyl-6-oxocyclo-hex-1-en-1-yl)(3-nitro-phen-yl)meth-yl]-5,5-dimethyl-cyclo-hex-2-en-1-one.

Project description:Each of the cyclohexenone rings in the title compound, C(23)H(27)NO(6), adopts a half-chair (envelope) conformation with the C atom carrying the methyl groups lying out of the plane defined by the five remaining C atoms; the O atoms lie to the same side of the mol-ecule as the respective >C(CH(3))(2) atoms. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of two intra-molecular O-H?O hydrogen bonds. In the crystal, the presence of C-H?O contacts leads to the formation of supra-molecular chains along the b axis. These aggregate into layers that stack along c.

Project description:In the title compound, C(22)H(24)O(5), each of the cyclo-hexenone rings adopts a half-chair conformation. The hy-droxy and carbonyl O atoms face each other and are orientated to allow for the formation of the two intra-molecular O-H?O hydrogen bonds which are typical of xanthene derivatives. In the crystal, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into layers parallel to the ab plane.

4-Chloro-2-((1R)-1-{[(R)-(2-chloro-phen-yl)(cyclo-pent-yl)meth-yl]amino}eth-yl)phenol.

Project description:The title compound, C(20)H(23)Cl(2)NO, was prepared by condensation of (R)-1-(2-chloro-phen-yl)-1-cyclo-pentyl-methanamine with 1-(5-chloro-2-hydroxy-phen-yl)ethanone, resulting in the formation of a new chiral center. The structural analysis confirms the absolute configuration of the title compound and the formation of the (R,R) diastereoisomer. There is an intra-molecular O-H⋯N hydrogen bond which stabilizes the conformation of the mol-ecule. The mol-ecules are linked to each other through weak C-H⋯π inter-actions.

9?-Hy-droxy-12-{[4-(4-hy-droxy-phen-yl)piperazin-1-yl]meth-yl}-4,8-dimethyl-3,14-dioxatri-cyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one.

Project description:The title compound, C25H34N2O5, was synthesized from 9?-hy-droxy-parthenolide (9?-hy-droxy-4,8-dimethyl-12-methylen-3, 14-dioxa-tri-cyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), which in turn was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule comprises a ten-membered ring fused to a five-membered ring with an additional ep-oxy ring system fused to the ten-membered ring. The five-membered ring also carries a 4-hy-droxy-phenyl-piperazin-1-ylmethyl substituent. The ten-membered ring adopts an approximate chair-chair conformation, while the piperazine ring displays a chair conformation and the five-membered ring shows an envelope conformation with the C atom closest to the hy-droxy group forming the flap. Two C atoms in the phenyl ring and the O atom of the hydroxyl group are disordered over two sites, with an occupancy ratio of 0.53?(5):0.47?(5). An intra-molecular O-H?N hydrogen-bond stabilizes the mol-ecular conformation. In the crystal, C-H?O hydrogen bonds link the mol-ecules into zigzag chains running along the a-axis direction.

Project description:In the title compound, C(24)H(29)BrO(6), the dihedral angle between the cyclo-hexenone mean planes is 57.63?(2)° while the dihedral angles between the benzene ring and the cyclo-hexenone mean planes are 58.42?(2) and 69.08?(3)°. The two cyclo-hexenone rings both show an envelope conformation, with the C atom bearing two methyl groups as the flap atom in each ring. Two intra-molecular O-H?O hydrogen bonds occur. In the crystal, molecules are linked via pairs of O-H?O hydrogen bonds, forming inversion dimers.

Project description:In the title compound, C(18)H(16)ClNO(4), the dihedral angle between the mean planes through the aromatic rings is 83.8?(8)°.

The mol-ecules are linked into centrosymmetric R(2) (2)(6) dimers via O-H?N hydrogen bonds. The crystal packing is further stabilized by C-H?O inter-actions.
