(2R,4R,7S,10R,12R*)-3,11,13,15-Tetra-oxa-penta-cyclo-[5.5.3.0(1,7).0(2,4).0(10,12)]penta-deca-5,8-dien-14-one.

ABSTRACT: The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H?O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C?O contacts [3.183?(4)?Å] between the C(?+)=O(?-) dipoles of neighbouring carbonate moieties.

The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H⋯O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C⋯O contacts [3.183 (4) Å] between the C(δ+)=O(δ-) dipoles of neighbouring carbonate moieties. ...[more]

Project description:The title compound, C16H24Cl2O, was synthesized in three steps from ?-himachalene (3,5,5,9-tetra-methyl-2,4a,5,6,7,8-hexa-hydro-1H-benzo-cyclo-heptene), which was isolated from essential oil of the Atlas cedar (cedrus atlantica). The asymmetric unit contains two independent mol-ecules with similar conformations. Each mol-ecule is built up from two fused seven-membered rings and an additional three-membered ring arising from the reaction of himachalene with di-chloro-carbene. The dihedral angles between the mean planes of the two seven-membered rings are 75.03?(9) and 75.02?(9)° in the two independent mol-ecules.

Project description:The title chiral quaternary ammonium salt, C(13)H(25)N(4) (+)·I(-), was synthesized through the Menschutkin reaction between the cage aminal (2S,7S)-1,8,10,12-tetra-aza-tetra-cyclo-[8.3.1.1(8,12).0(2,7)]penta-decane and ethyl iodide. The quaternization occurred regioselectively on the nitrogen with major sp3 character. The crystal structure consists of anions and cations separated by normal distances. Ions are not linked through C-H⋯I hydrogen bonds.

(1S*,3S*,8S*,10S*)-10-Fluoro-15-oxa-tetra-cyclo-[6.6.1.0.0]penta-deca-5,12-dien-3-ol.

Project description:The title compound, C(14)H(17)FO(2), was obtained from anti-4a,9a:8a,10a-diep-oxy-1,4,4a,5,8,8a,9,9a,10,10a-deca-hydro-anthra-cene via tandem hydrogen-fluoride-mediated epoxide ring-opening and transannular oxacyclization. With the two cyclo-hexene rings folded towards the oxygen bridge, the title tetra-cyclic fluoro-alcohol mol-ecule displays a conformation remin-iscent of a pagoda. The crystal packing is effected via inter-molecular O-H?O hydrogen bonds, which link the mol-ecules into a zigzag chain along the b axis.

Penta-carbonyl-2κC-chlorido-1κCl-bis-[1(η)-cyclo-penta-dien-yl][μ-oxido(phenyl)methylene-1:2κO:C]hafnium(IV)tungsten(0).

Project description:The title compound, [HfW(C(5)H(5))(2)(C(7)H(5)O)Cl(CO)(5)] or [W(CO)(5)(C(7)H(5)O){Hf(C(5)H(5))(2)Cl}], contains two metal centres, with a (tungstenpenta-carbon-yl)oxy-phenyl-carbene unit coordinated to a hafnocene chloride.

Project description:The title compound, C(25)H(33)ClN(2)O(5), was synthesized from 9α-hy-droxy-parthenolide (9α-hy-droxy-4,8-dimethyl-12-methyl-ene-3,14-dioxatricyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), which was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule is built up from fused five- and ten-membered rings with two additional ep-oxy ring systems and a chloro-phenyl-piperazine group as a 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. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯N hydrogen bond between the hy-droxy group and a piperazine N atom. The crystal structure is stabilized by weak C-H⋯O inter-actions.
