2-Chloro­quinoline-3-carboxylic acid

The crystal structure of the title compound, C(10)H(6)ClNO(2), can be described by two types of crossed layers which are parallel to (110) and (10). The crystal packing is stabilized by inter-molecular C-H⋯O and O-H⋯N hydrogen bonds, resulting in the formation of a two-dimensional network and reinforcing the cohesion of the structure.

2-Bromo­pyridine-3-carboxylic acid

The carboxylic acid residue in the title compound, C(6)H(4)BrNO(2), is twisted out of the plane of the other atoms, as indicated by the (Br)C-C-C-O(carbon-yl) torsion angle of -20.1 (9)°. In the crystal, supra-molecular chains mediated by O-H⋯N hydrogen bonds are formed with base vector [201] and C-H⋯O inter-actions reinforce the packing.

2-(Phenyl­sulfan­yl)pyridine-3-carboxylic acid

The title compound, C(12)H(9)NO(2)S, belongs to the nitro-gen-containing group of heterocyclic organic compounds and crystallized with two mol-ecules per asymmetric unit. In the crystal, both molecules form inversion dimers linked by pairs of O-H-O hydrogen bonds. Weak symmetry-related C-H-O inter-actions link the carboxyl dimers along b axis. The dihedral angle between the two aromatic rings i...

2-(Carboxy­methyl­sulfan­yl)pyridine-3-carboxylic acid monohydrate

The title compound, C(8)H(7)NO(4)S·H(2)O, was obtained by reaction of 2-mercaptopyridine-3-carboxylic acid with chloro-acetic acid. In the mol-ecular structure, the dihedral angle between the two least-squares planes defined by the pyridine ring and the carb-oxy group is 8.32 (9)°. The carboxy-methyl-sulfanyl group makes a torsion angle of 82.64 (12)° with the pyridine ring. An intra-molecular ...

SYNTHESIS OF 3-ARYLMETHYL-4- THIAZOLIDINE-CARBOXYLIC ACID-2-ONES AND 2-THIONES

Barium salts of dibenzylidene cystines 8a-c were obtained from the reaction of Lcystine with benzaldehyde or its derivatives in the presence of barium hydroxide. Their reduction with zinc and hydrochloric acid in methanol yielded the Narylmethylcysteines ?9a-c?. These can, in turn, be converted by esterification into the methyl esters ?10 a-c. ?Reaction of N, N'-carbonyl diimidazole (Im C...
