The quinolinyl fused-ring of the title compound, C(11)H(8)ClNO, is almost planar (r.m.s. deviation = 0.013 Å); the formyl group is slightly bent out of the plane of the fused ring system [C-C-C-O torsion angle = 13.5 (4)°].
متن کاملHigh-spin intermediates of the photolysis of 2,4,6-triazido-3-chloro-5-fluoropyridine
In contrast to theoretical expectations, the photolysis of 2,4,6-triazido-3-chloro-5-fluoropyridine in argon at 5 K gives rise to EPR peaks of just two triplet mononitrenes, two quintet dinitrenes, and a septet trinitrene. EPR spectral simulations in combination with DFT calculations show that observable nitrenes can be assigned to triplet 2,4-diazido-3-chloro-5-fluoropyridyl-6-nitrene (D T = 1...

In the title compound, C13H12ClNO2, the dihedral angle between the planes of the quinoline ring system (r.m.s. deviation = 0.029 Å) and the ester group is 54.97 (6)°. The C-O-C-Cm (m = meth-yl) torsion angle is -140.62 (16)°. In the crystal, mol-ecules inter-act via aromatic π-π stacking [shortest centroid-centroid separation = 3.6774 (9) Å] generating (010) sheets.
متن کاملCrystal packing in three related disaccharides: precursors to heparan sulfate oligosaccharides
The three title compounds form part of a set of important precursor dissacharides which lead to novel therapeutics, in particular for Alzheimer's disease. All three crystallize as poorly diffracting crystals with one independent mol-ecule in the asymmetric unit. Two of them are isostructural: 4-meth-oxy-phenyl 4-O-[6-O-acetyl-2-azido-3-O-benzyl-2-de-oxy-4-O-(9-fluor-en-yl-methyl-oxycarbon-yl)-α...
