(1R,3R,4R,6S)-4-(7-Meth-oxy-2-oxo-2H-chromen-6-yl)-1-methyl-3,6-dioxa-bicyclo-[3.1.0]hexan-2-yl acetate.

ABSTRACT: In the title compound, C17H16O7, which was isolated from the leaves of Micromelum integerrimum, the furan ring adopts an envelope conformation with the O atom as the flap. An intra-molecular C-H?O hydrogen bond occurs. The carbonyl O atom is disordered in a 0.57?(8):0.43?(8) ratio. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds into a C(10) chain along [010].

(1S,5R)-1-(3,4-Dichloro-phen-yl)-3-oxa-bicyclo-[3.1.0]hexan-2-one.

Project description:The absolute structure has been determined by X-ray analysis for the title compound, C(11)H(8)Cl(2)O(2). The five-membered ring of the mol-ecule is best described as a flattened envelope conformation with the methyl-ene C atom located 0.208 (2) Å below the plane formed by the other four atoms. A weak intermolecular C-H⋯O hydrogen bond is present in the crystal structure.

(1R,2R,3R,4R,5S)-2,3-Bis[(2S')-2-acet-oxy-2-phenyl-acet-oxy]-4-azido-1-[(2,4-dinitro-phen-yl)hydrazono-meth-yl]bicyclo-[3.1.0]hexa-ne.

Project description:In the title compound, C(38)H(29)N(7)O(12), the five-membered ring adopts an envelope conformation in which the 'flap' is cis to the cyclo-propane group. This conformation is similar to those of other bicyclo-[3.1.0]hexane analogues for which crystal structures have been reported. The absolute configuration of the stereogenic centers on the cyclo-pentane ring, as determined by comparison with the known configurations of the stereogenic centers in the (2S)-2-acet-oxy-2-phenyl-acet-oxy groups, is 1(R), 2(R), 3(R), 4(R) and 5(S). An intramolecular N-H⋯O hydrogen bond is present.

Project description:The mol-ecule of the title compound, C(26)H(28)O(5), is chiral with five stereogenic centres; however, the centrosymmetric triclinic group gives a racemic crystal. The fused ring system adopta boat conformation in which the cyclo-propane ring plane is roughly perpendicular to the styryl group plane, forming a dihedral angle of 74.78 (19)°. The dihedral angle between the two benzene rings is 77.24 (6)°.

Project description:In the title compound, C(27)H(30)O(14)·H(2)O, the hydroxy-phenyl ring makes a dihedral angle of 20.05?(11)° with the chromenone ring system. The crystal structure is stabilized by intra- and inter-molecular O-H?O hydrogen bonds. The absolute configuration was assigned on the basis of an analagous structure.

Project description:In the title compound, C(17)H(19)NO(3), the isoxazolidine ring adopts an envelope conformation with the O atom as the flap. In the crystal, O-H⋯O hydrogen bonds form C(2) (3)(14) R(2) (2)(14) motifs.

Project description:In the title compound, C(17)H(19)NO(7), the cyclo-pentane ring is in an envelope conformation in which the methyl-ene group forming the flap is cis to the cyclo-propane group. The relative configuration between the 4-nitro-benzo-yloxy substituent on the side chain and the cyclo-propane ring is trans and the methoxy-lmethyl group adopts the expected conformation in which the two O atoms are gauche to one another.

Project description:The relative configuration of the endo isomer of the title compound, C(9)H(14)O(4)S, has been established and the conformation of the diastereoisomer is discussed. The five-membered ring adopts an envelope conformation. The conformation of the methane-sulfonate substituent is stabilized by inter-molecular C-H?O hydrogen bonds. The crystal packing results in alternating layers of polar methane-sulfonates and stacked bicyclo-hexa-nyl rings parallel to ab.

[(1S,2S,3R,4R)-3-Hydr-oxy-4,7,7-tri-methyl-bicyclo-[2.2.1]heptan-2-yl]methyl[(E)-3-(trimethyl-silyl)prop-2-enyl]selen-onium bromide.

Project description:The title compound, a seleno-nium bromide, C(17)H(33)OSeSi(+)·Br(-), was obtained from the reaction of enanti-omerically pure 4,7,7-trimethyl-2-methyl-selanylbicyclo-[2.2.1]heptan-3-ol and (3-bromopropen-yl)trimethyl-silane in acetone. Due to the chiral bicyclic substituent, the crystal structure is not centrosymmetric and has no symmetry plane, with four chiral C atoms in the cation. The asymmetric unit contains one seleno-nium cation and one bromide anion. C-H?Br and O-H?Br hydrogen bonds link the ions, forming a one-dimensional R-helical chain-like supra-molecular structure.

4,4'-[(2R*,3R*,4R*,5R*)-3,4-Dimethyl-tetra-hydro-furan-2,5-di-yl]diphenol.

Project description:The title mol-ecule, C(18)H(20)O(3), is a furan-oid lignan extracted from the leaves of Larrea tridentata. The relative absolute configuration for the four chiral centers was established, showing that this compound is 4-epi-larreatricin, which has been previously reported in the literature. The mol-ecule displays noncrystallographic C(2) symmetry, with the methyl and phenol substituents alternating above and below the mean plane of the furan ring. The conformation of this ring is described by the pseudorotation phase angle P = 171.3° and the maximum out-of-plane pucker ?(m) = 37.7°. These parameters indicate that the furan ring adopts the same conformation as the ribose residues in B-DNA. The packing is dominated by inter-molecular O-H?O hydrogen bonds. The phenol hy-droxy groups form chains in the [110] direction and these chains inter-act via O-H?O(furan) contacts.
