(3R,4S,5S)-4-Hydr-oxy-3-methyl-5-[(2S,3R)-3-methyl-pent-4-en-2-yl]tetra-hydro-furan-2-one.

Project description:The title compound, C(11)H(18)O(3), was synthesized to prove the relative configuration of the corresponding acyclic C1-C8 stereopentade. It crystallizes with two mol-ecules in the asymmetric unit, which show only slight differences. The mol-ecules are linked via O-H⋯O hydrogen bonds, resulting in two crystallographically independent chains of mol-ecules propagating in the a-axis direction. The absolute configuration was known from the synthesis.

(2S,3R,4S,4aR)-2,3,4,7-Tetra-hydroxy-3,4,4a,5-tetra-hydro-[1,3]dioxolo[4,5-j]phenanthridin-6(2H)-one hemihydrate.

Project description:The title natural compound, isolated from Narcissus pseudonarcissus var. King Alfred crystallizes as a hemihydrate, C14H13NO7·0.5H2O, with four crystallographically independent dioxolophenanthridinone mol-ecules and two crystallographically independent solvent water mol-ecules in the asymmetric unit. All four crystallographically independent dioxolophenanthridinone mol-ecules are geometrically very similar and differ only in the orientations of the three hy-droxy groups at the terminal cyclo-hexene rings. The five-membered dioxolane ring has a planar conformation (the r.m.s. deviations are 0.010, 0.019, 0.025 and 0.004?Å, for the four crystallographically independent molecules), and the six-membered dihydro-pyridone and cyclo-hexene rings adopt sofa conformations in each mol-ecule. The flattened structure of each dioxolophenanthridinone mol-ecule is supported by a strong intra-molecular O-H?O hydrogen bond. The N atom has a slightly pyramidalized configuration. In the crystal, the dioxolophenanthridinone mol-ecules form layers parallel to (101) with O-H?O and N-H?O hydrogen bonds linking the dioxolophenanthridinone mol-ecules both within and between the layers and the water mol-ecules, forming a three-dimensional framework. The absolute configurations of the chiral centers are 2S, 3R, 4S and 4aR.

Project description:The crystal structure of the title compound, C(6)H(11)NO(5), establishes the relative configuration at the four stereogenic centres; the absolute configuration is determined by the use of d-glucuronolactone as the starting material for the synthesis. Mol-ecules are linked by inter-molecular O-H?O and N-H?O hydrogen bonds into a three-dimensional network, with each mol-ecule acting as a donor and acceptor for five hydrogen bonds.

Crystal structure of [(2R,3R,4S)-3,4-bis(acet-yloxy)-5-iodo-3,4-di-hydro-2H-pyran-2-yl]methyl acetate.

Project description:In the title compound, C12H15IO7, the 3,4-di-hydro-2H-pyran ring is in a distorted half-boat conformation with the atom bearing the acet-yloxy group adjacent to the C atom bearing the methyl-acetate group lying 0.633 (6) Å above the plane of the remaining ring atoms (r.m.s. deviation = 0.0907 Å). In the crystal, mol-ecules are linked into a supra-molecular chain along the a axis through two C-H⋯O inter-actions to the same acceptor carbonyl O atom; these chains pack with no specific inter-molecular inter-actions between them.

(2S,3R)-3-(2-Bromo-phen-yl)-2-nitro-2,3,6,7-tetra-hydro-1-benzo-furan-4(5H)-one.

Project description:The title compound, C14H12BrNO4, has two chiral C atoms. The C atom next to the O atom in the di-hydro-furan ring has an S configuration, while the adjacent chiral C atom has an R configuration. The cyclo-hex-2-enone and di-hydro-furan rings both adopt envelope conformations, with the flap atoms (middle CH2 in cyclo-hex-2-enone and NO2-substituted C in di-hydro-furan) lying 0.612 (3) and 0.295 (2) Å, respectively, from the mean plane of the remaining atoms. The dihedral angle between the mean planes of the furan and benzene rings is 80.0 (3)°. In the crystal, the mol-ecules are linked by C-H⋯O inter-actions, generating a three-dimensional network.

Penta-fluoro-phenyl (3R,4R,5S)-5-{[(3R,4R,5S)-5-azido-methyl-3,4-dimeth-oxy-2,3,4,5-tetra-hydro-furan-3-carboxamido]-meth-yl}-3,4-dimeth-oxy-2,3,4,5-tetra-hydro-furan-3-carboxyl-ate.

Project description:The title compound, C(22)H(25)F(5)N(4)O(9), is a stable penta-fluoro-phenyl ester inter-mediate in the synthesis of novel homo-oligomeric structures containing branched carbon chains. The structure is epimeric to the previously characterized dimeric penta-fluoro-phenyl ester with stereochemistry (3R,4R,5R), which was synthesized using d-ribose as starting material. The crystal structure of the title mol-ecule removes any ambiguities arising from the relative stereochemistries of the six chiral centres. Two hydrogen bonds, bifurcating from the NH group, stabilize the crystal: one intra-molecular and one inter-molecular, both involving O atoms of the meth-oxy groups. The asymmetric unit contains two independent mol-ecules not related by any pseudo-symmetry operators. The major conformational differences are localized, leading to one mol-ecule being extended compared to the other. The collected crystal was twinned (twin ratio is 0.939:0.061), and the azide group is positionally disordered over two positions in one mol-ecule [occupancy ratio 0.511?(18):0.489?(18)].

In the crystal structure, mol-ecules are linked by inter-molecular O-H?Br and N-H?Br hydrogen bonds, forming double chains around the twofold screw axes along the b-axis direction. Intra-molecular O-H?O inter-actions occur.

Project description:The title compound, C11H18O5, was isolated from a liquid culture of Pestalotiopsis sp. In the mol-ecule, the pyran-2-one ring assumes a half-chair conformation.

In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds forming a three-dimensional network.
