In the title compound, C(17)H(13)NO(2), the dihedral angle between the plane of the carb-oxy group and the quinoline mean plane is 45.05 (13)°, and that between the toluene ring mean plane and the quinoline mean plane is 25.29 (7)°. In the crystal, molecules are linked via O-H⋯.N hydrogen bonds, forming chains propagating along the b-axis direction. These chain are linked via C-H⋯O interactions...

In the title hydrate, C17H13N3O·H2O, the dihedral angle between the quinoline and benzimidazole ring systems is 6.22 (7)°. The water mol-ecule is linked to the main mol-ecule by N-H⋯O and O-H⋯N hydrogen bonds. Further O-H⋯N hydrogen bonds link the organic molecules into C(6) chains running parallel to the b axis.

In the title salt, C(21)H(18)ClNO, the quinoline ring system is approximately planar [maximum deviation = 0.035 (2) Å], and forms a dihedral angle of 71.42 (6)° with the attached phenyl ring. The cyclo-hexa-none ring exists in a half-boat conformation. In the crystal packing, C-H⋯O contacts link the mol-ecules into extended supra-molecular chains along the c axis.

Asymmetric hydrogenation of (hetero)arenes is one of the most straightforward ways to synthesize enantiomerically pure, saturated or partially saturated cyclic molecules. Recent progress has significantly expanded the substrate scope of this reaction. Whereas a number of highly efficient catalytic systems have been found for the asymmetric hydrogenation of quinolines, structurally related isoqu...

A facile synthesis of 4-aryl substituted oxazolo[4,5-c]quinolines has been described via a modified Pictet-Spengler method and using Cu(TFA)2 as a catalyst. The developed methodology directly functionalizes the C-4 position of oxazoles without the aid of any prefunctionalization, in the presence of the more reactive C-2 position in good yields. The versatility of the established method has been...

The title compound, C(7)H(7)ClN(2)O(4)S, is of inter-est as a precursor to biologically active substituted quinolines. Its structure resembles those of the previously reported N-phenyl-methane sulfonamide and its 4-nitro, 4-fluoro and 4-bromo derivatives, with slightly different geometric parameters. An intra-molecular N-H⋯O hydrogen bond gives rise to a six-membered ring. Inter-molecular C-H⋯O...

The susceptibility of 10 multiply antibiotic-resistant strains of Streptococcus pneumoniae to several quinoline antibiotics and to coumermycin, novobiocin, and penicillin was determined. The MIC of penicillin for all test isolates was greater than or equal to 4 micrograms/ml. Ciprofloxacin was the most active quinoline derivative tested, followed by norfloxacin. These isolates of S. pneumoniae ...

the first highly accelerated niementowski reaction of anhranilic acid with some amides or ketones under microwave irradiation leading to quinazolinones and quinoline derivatives is described. these reactions represent some examples of efficient microwave irradiation promoted organic condensation in which the reactions can be carried out in open vessels and provides products of high purity with ...
