The title compound, C(20)H(14)Cl(4)O, was prepared from a mixture of 2,4-dichloro-benzophenone and cyclo-hexa-none. The dihedral angles formed by the cyclohexane ring and two benzene rings are 39.18 (2) and 60.72 (2)°. There are some weak intra-molecular C-H⋯O and C-H⋯Cl hydrogen-bond contacts in the crystal structure.

The title compound, C(23)H(18)BrN, was synthesized by the reaction of 4-bromo-benzaldehyde, naphthalen-2-amine and cyclo-hexa-none in tetra-hydro-furan, catalyzed by iodine. The saturated six-membered ring adopts a half-chair conformation, and the four vicinal rings form a helical conformation, which results in a significant deviation from planarity for the pyridine ring. In the crystal, a weak...

In the title compound, C(42)H(33)NO(2), the six-membered cyclo-hexa-none ring adopts a slightly distorted chair conformation and the five-membered pyrrolidine ring is in an envelope conformation. The mol-ecular structure features four intra-molecular C-H⋯O inter-actions and an intra-molecular C-H⋯π inter-action. Furthermore, the crystal packing is stabilized by an inter-molecular C-H⋯O and thre...

The title compound, C17H24Br2Cl2, was synthesized from β-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-heptene), which was isolated from the essential oil of the Atlas cedar (Cedrus Atlantica). The mol-ecule contains fused six-, seven- and two three-membered rings. The six-membered ring has a half-chair conformation, while the seven-membered ring displays a boat confo...

The mol-ecule of the title compound, C11H15NO, contains a cyclo-hexa-none ring, three defined stereocenters and an exocyclic double bond. The crystal structure is the result of a study on the Michael addition reaction of (S)-carvone with sodium cyanide using ionic liquids as the reaction medium and so the absolute configuration is known from the chemistry. The six-membered ring is in a chair co...

In the title compound, C(17)H(24)NO(+)·Cl(-), the cyclo-hexa-1,4-diene ring, which is almost planar, with a maximum deviation of 0.024 (4) Å from the mean plane, makes a dihedral angle of 66.4 (1)° with the benzene ring. In the crystal, inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds link the mol-ecules into an infinite chain along the b axis.

In the title compound {systematic name: methyl 1-[12-oxo-10-(3,4,5-trimethoxy-phen-yl)-4,6,13-trioxa-tetra-cyclo-[7.7.0.0(3,7).0(11,15)]hexa-deca-1,3(7),8-trien-16-yl]-1H-1,2,3-triazole-4-carboxyl-ate dichloro-methane solvate}, C(26)H(25)N(3)O(9)·CH(2)Cl(2), the tetra-hydro-furan ring and the six-membered ring fused to it both display envelope conformations.

In the crystal of the title compound, C(6)H(14)N(+)·C(2)Cl(3)O(2) (-), centrosymmetric assemblies of two cyclo-hexa-naminium cations and two trichloro-acetate ions are linked by N-H⋯O hydrogen bonds, thereby forming R(4) (4)(12) ring motifs. Further N-H⋯O inter-actions link the tetra-mers into chains propagating along the a axis.

There are two independent molecules in the asymmetric unit of the title cyclo-hexa-none derivative, C(14)H(24)OS, in which both cyclo-hexane rings exhibit chair conformations. They are also equatorial to each other, which permits the ethanethiol substituent to be in a syn conformation with the α-H atom of the parent attached cyclo-hexa-none.

In the title compound, C(32)H(28)N(2)O(2), the pyrrolidine ring adopts an envelope conformation, whereas the cyclo-hexa-none ring in the tetra-hydro-naphthalene fused-ring system adopts a half-chair conformation. The oxindole ring system is oriented at an angle of 48.2 (1)° with respect to the naphthyl ring system. An intra-molecular C-H⋯O close contact is observed. In the crystal, mol-ecules a...
