2-Chloro-7,8,9,10-tetra-hydro-cyclo-hepta-[b]indol-6(5H)-one.

ABSTRACT: In the title mol-ecule, C(13)H(12)ClNO, the dihedral angle between the benzene and pyrrole rings is 1.38?(9)°. The cyclo-heptene ring adopts a distorted twist chair and sofa conformation. Inter-molecular N-H?O hydrogen bonds form an R(2) (2)(10) loop in the crystal packing. Further, weak C-H?O and C-H?? (involving the benzene ring) inter-actions are found in the crystal structure.

7,8,9,10-Tetra-hydro-2-methyl-cyclo-hepta-[b]indol-6(5H)-one.

Project description:The title compound, C(14)H(15)NO, was synthesized from 2-hydroxy-methyl-enecyclo-hepta-none via a Japp-Klingemann acid-catalyzed cyclization. The seven-membered ring exhibits a slightly distorted envelope conformation. N-H?O hydrogen bonds form a centrosymmetric dimer; C-H?O hydrogen bonds and ?-? stacking inter-actions (the centers of the atoms involved in the stacking interaction are separated by 3.504?Å) give rise to another type of centrosymmetric dimer. In combination, these inter-actions create a stair-like chain of mol-ecules that inter-acts only loosely with neighboring chains via van der Waals inter-actions and weak C-H?? contacts.

Crystal structures of 2-benzyl-amino-4-(4-bromo-phen-yl)-6,7,8,9-tetra-hydro-5H-cyclo-hepta-[b]pyridine-3-carbo-nitrile and 2-benzyl-amino-4-(4-chloro-phen-yl)-6,7,8,9-tetra-hydro-5H-cyclo-hepta[b]pyridine-3-carbo-nitrile.

Project description:In the title compounds, C24H22BrN3, (I), and C24H22ClN3, (II), the 2-amino-pyridine ring is fused with a cyclo-heptane ring, which adopts a half-chair conformation. The planes of the phenyl and benzene rings are inclined to that of the central pyridine ring [r.m.s. deviations = 0.0083 (1) and 0.0093 (1) Å for (I) and (II), respectively] by 62.47 (17) and 72.51 (14)°, respectively, in (I), and by 71.44 (9) and 54.90 (8)°, respectively, in (II). The planes of the aromatic rings are inclined to one another by 53.82 (17)° in (I) and by 58.04 (9)° in (II). In the crystals of both (I) and (II), pairs of N-H⋯Nnitrile hydrogen bonds link the mol-ecules, forming inversion dimers with R 2 (2)(12) ring motifs. In (I), the resulting dimers are connected through C-H⋯Br hydrogen bonds, forming sheets parallel to (10-1), and π-π inter-actions [inter-centroid distance = 3.7821 (16) Å] involving inversion-related pyridine rings, forming a three-dimensional network. In (II), the resulting dimers are connected through π-π inter-actions [inter-centroid distance = 3.771 (2) Å] involving inversion-related pyridine rings, forming a two-dimensional network lying parallel to (001).

2-(4-Bromo-phen-yl)-4-(4-meth-oxy-phen-yl)-6,7,8,9-tetra-hydro-5H-cyclo-hepta-[b]pyridine.

Project description:In the title compound, C23H22BrNO, the cyclo-heptane ring adopts a chair conformation. The pyridine ring makes dihedral angles of 58.63 (15) and 8.27 (16)° with the benzene rings. The dihedral angle between the benzene rings is 56.68 (17)°. The crystal packing features C-Br⋯π inter-actions [Br⋯centroid distances= 3.813 (2) and 3.839 (2) Å; C-Br⋯centroid = 126.25 (10) and 138.31 (10)°, respectively, forming a three dimensional supramolecular architecture.

Crystal structure of 2-benzyl-amino-4-(4-meth-oxy-phen-yl)-6,7,8,9-tetra-hydro-5H-cyclo-hepta-[b]pyridine-3-carbo-nitrile.

Project description:The title compound, C25H25N3O, comprises a 2-amino-pyridine ring fused with a cyclo-heptane ring, which adopts a chair conformation. The central pyridine ring (r.m.s. deviation = 0.013?Å) carries three substituents, viz. a benzyl-amino group, a meth-oxy-phenyl ring and a carbo-nitrile group. The N atom of the carbo-nitrile group is significantly displaced [by 0.2247?(1)?Å] from the plane of the pyridine ring, probably due to steric crowding involving the adjacent substituents. The phenyl and benzene rings are inclined to one another by 58.91?(7)° and to the pyridine ring by 76.68?(7) and 49.80?(6)°, respectively. In the crystal, inversion dimers linked by pairs of N-H?Nnitrile hydrogen bonds generate R 2 (2)(14) loops. The dimers are linked by C-H?? and slipped parallel ?-? inter-actions [centroid-centroid distance = 3.6532?(3)?Å] into a three-dimensional structure.

1,3-Dimethyl-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[c]thio-phene-4,8-dione.

Project description:In the title compound, C(11)H(12)O(2)S, the C and S atoms of the central thio-phene and the methyl groups, and the two carbonyl groups of the cyclo-hepta-nedione are almost coplanar [maximum deviation from the mean plane = 0.221?(2)?Å]. The packing is stabilized by ?-? inter-actions between the conjugated thio-phenes, the shortest centroid-centroid distance between thio-phene rings being 3.9759?(10)?Å.

Project description:The title compound, C(17)H(22)O(2), was semi-synthesized from a mixture of ?-atlantone (Z) and ?-atlantone (E), which were isolated from the essential oil of the Atlas cedar (cedrus atlantica).
