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...
متن کامل2-(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 ...
متن کامل2-Methyl-4-oxo-6,7,8,9-tetrahydrothieno[2′,3′:4,5]pyrimidino[1,2-a]pyridine-3-carboxylic acid
There are two independent mol-ecules in the asymmetric unit of the title compound, C(12)H(12)N(2)O(3)S. With the exception of the methyl-ene groups, a mean plane fitted through all non-H atoms of each mol-ecule has an r.m.s. deviation of 0.035 Å for one mol-ecule and 0.120 Å for the second. In one of the independent mol-ecules, the methyl-ene groups was refined using a disorder model with an oc...
متن کاملSynthesis of 1-methyl-3-oxo-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylic acid methyl ester.
A simple and efficient method for the preparation of 1-methyl-3-oxo-7- oxabicyclo[2.2.1]hept-5-en-2-carboxylic acid methyl ester (1) is described. The first step is a highly regioselective Diels-Alder reaction between 2-methylfuran and methyl-3-bromo- propiolate. A remarkably difficult ketal hydrolysis reaction was effected by treatment with HCl, a simple reagent that was shown to be more effic...
متن کامل1-Methyl-1H-indazole-3-carboxylic acid
The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.
