7-Hy-droxy-8-isopropyl-1,1,4a-trimethyl-4a,9,10,10a-tetra-hydro-phenanthren-2(1H)-one.

ABSTRACT: The title compound, C(20)H(26)O(2), was isolated from a chloro-form extract of Tetra-clinis articulata wood. The mol-ecule contains three fused rings which exhibit different conformations. The non-aromatic oxo-substituted ring has a screw-boat conformation, while the central ring has a half-chair conformation. In the crystal, mol-ecules are linked to each other by inter-molecular O-H?O hydrogen bonds involving the carbonyl and hy-droxy groups.

Project description:In the xanthene ring system in the title compound, C19H18O4, the 4H-pyran ring has a maximum deviation of 0.110?(2)?Å from planarity and the cyclo-hexene ring exhibits a puckered conformation [puckering parameters Q T = 0.452?(3)?Å, ? = 57.0?(4) and ? = 131.7?(4)°]. The cyclo-hexene ring attached to the xanthene system adopts an envelope conformation, with the middle of the three methylene C atoms as the flap atom. In the crystal, O-H?O and C-H?O hydrogen bonds form infinite chains of R 1 (2)(6) ring motifs along [100] with the xanthene groups arranged in an alternating zigzag manner.

6-Hydr-oxy-7-isopropyl-1,1,4a-trimethyl-2,3,4,4a,10,10a-hexa-hydro-phenanthren-9(1H)-one.

Project description:The title compound, C(20)H(28)O(2), commonly named Sugiol, is a natural oxygenated diterpene that we have isolated for the first time from a hexane extract of the fruits of Juniperus Oxycedrus L. Its X-ray crystal structure determination confirms an abietane skeleton which was predicted by spectroscopic analysis, mainly by (1)H and (13)C NMR. The cyclo-hexane ring adopts a flattened chair conformation, while the cyclo-hexene ring adopts an envelope conformation. The mol-ecules are linked through O-H⋯O hydrogen bonds to form a zigzag chain extending parallel to the c axis.

Project description:The asymmetric unit of the title compound, C(18)H(18)N(2)O(2), contains three independent mol-ecules. In each, the seven-membered diazepine ring adopts a boat conformation with the hy-droxy-substituted C atom at the prow and fused-ring C atoms at the stern. In the crystal, the mol-ecules are linked by O-H?O and N-H?O hydrogen bonds. The allyl group of one mol-ecule is equally disordered over two positions.

Project description:The pyridine ring in the title compound, C(39)H(47)NO(7)·0.5C(2)H(5)OH·0.5 H(2)O, is connected to one 3,3,6,6-tetra-methyl-1,8-dioxoxanthenyl and one 4a-hy-droxy-3,3,6,6-tetra-methyl-1,8-dioxodeca-hydroxanthenyl substituent in the 2- and 6-positions of the ring. In the former substituent, the six-membered xanthenyl ring adopts a flattened envelope conformation (with the methine C atom as the flap) while in the latter, the six-membered xanthenyl ring adopts a twisted envelope conformation (with the C atom bearing the hy-droxy group representing the flap). The hy-droxy H atom forms an intra-molecular hydrogen bond to the pyridyl N atom. An ethanol solvent mol-ecule is disordered with respect to a water mol-ecule in a 1:1 ratio. The water mol-ecule itself is disordered over two positions of equal occupancy.

Crystal structure of 3-hy-droxy-methyl-1,2,3,4-tetra-hydro-isoquinolin-1-one.

Project description:In the title compound, C10H11NO2, two independent but virtually superimposable mol-ecules, A and B, comprise the asymmetric unit. The heterocyclic ring in each mol-ecule has a screw-boat conformation, and the methyl-hydroxyl group occupies a position to one side of this ring with N-C-C-O torsion angles of -55.30 (15) (mol-ecule A) and -55.94 (16)° (mol-ecule B). In the crystal, O-H⋯O and N-H⋯O hydrogen bonding leads to 11-membered {⋯HNCO⋯HO⋯HNC2O} heterosynthons, involving three different mol-ecules, which are edge-shared to generate a supra-molecular chain along the a axis. Inter-actions of the type C-H⋯O provide additional stability to the chains, and link these into a three-dimensional architecture.

6-Hy-droxy-5,7,8-trimethyl-chroman-2-one.

Project description:The title compound, C(12)H(14)O(3), consists of a chromanone unit with an -OH substituent at the 4-position and methyl substituents on the remaining C atoms of the aromatic ring. The fused pyran-one ring adopts a distorted envelope conformation with the methyl-ene group adjacent to the carbonyl carbon as the flap atom. The crystal structure is stabilized by classical O-H?O hydrogen bonds and weak C-H?O and C-H?? inter-actions, generating a three-dimensional network.

(4R)-3-Hy-droxy-7-isopropyl-4-methyl-5,6-di-hydro-benzo-furan-2(4H)-one.

Project description:In the title compound, alternatively called ?-hy-droxy-?-alkyl-idenebutenolide, C12H16O3, two independent mol-ecules (A and B) crystallize in the asymmetric unit in each of which the 5,6-di-hydro-benzo ring has an envelope conformation. The torsion angle along the butadiene chain in the ?-alkyl-idenebutenolide core is -177.9?(2)° for mol-ecule A and 179.9?(2)° for mol-ecule B. In the crystal, O-H?O hydrogen bonds between hy-droxyl and carbonyl groups of adjacent independent mol-ecules form dimers with R (2) 2(10) loops.

4a-Methyl-2,3,4,4a-tetra-hydro-1H-carbazole-6-sulfonamide.

Project description:In the title mol-ecule, C(13)H(16)N(2)O(2)S, the nine non-H atoms comprising the indole residue are approximately coplanar (r.m.s. deviation = 0.031?Å). The partially saturated ring adopts a chair conformation. One amine H forms an inter-molecular N-H?O hydrogen bond to a sulfonamide O atom, while the other amine H form is connected to the indole N atom of an adjacent mol-ecule via an N-H?N hydrogen bond, resulting in a three-dimensional architecture.

7-Hy-droxy-1,2,3,4-tetra-hydro-quinolin-2-one dihydrate.

Project description:The asymmetric unit of the title compound, C(9)H(9)NO(2)·2H(2)O, comprises two independent organic mol-ecules and four water mol-ecules of crystallization. The heterocyclic rings are not planar: in one mol-ecule, the C atom bearing the O atom and the adjacent methyl-ene C atom are displaced by 0.320?(3) and 0.677?(3)?Å, respectively, from the other eight atoms of the fused ring system. Equivalent values of 0.243?(3) and 0.659?(3)?Å apply to the second mol-ecule. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network.

9-(2-Hy-droxy-4,4-dimethyl-6-oxocyclo-hex-1-en-1-yl)-3,3-dimethyl-2,3,4,9-tetra-hydro-1H-xanthen-1-one.

Project description:The cyclo-hexene ring that constitutes a part of the tetra-hydroxanthene fused-ring system of the title compound, C(23)H(26)O(4), adopts a flattened half-chair conformation that approximates an envelope conformation (in which the methyl-ene C atom bearing the two methyl substituents represents the flap) as five of the six atoms lie approximately on a plane (r.m.s. deviation = 0.020?Å). The mean plane of the cyclo-hexene ring with the hy-droxy substituent is approximately perpendicular to the mean plane of the tetra-hydroxanthene system. In the crystal, adjacent mol-ecules are linked by O-H?O(carbon-yl) hydrogen bonds into a chain running along the b axis.
