2-(2-Chlorophenyl)-5-methyl-1,3-dioxane-5-carboxylic acid
In the title compound, C(12)H(13)ClO(4), the 1,3-dioxane ring adopts a chair conformation and the 2-chloro-benzene and methyl substituents occupy equatorial sites. The carboxyl group is in an axial inclination. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
متن کامل5-(Methoxycarbonyl)thiophene-2-carboxylic acid
In the title compound, C(7)H(6)O(4)S, a monoester derivative of 2,5-thio-phene-dicarboxylic acid, the carboxylic acid and the carboxylic acid ester groups are approximately coplanar with thio-phene ring, making a dihedral angle of 3.1 (4) and 3.6 (4)°, respectively. In the crystal structure, mol-ecules are connected by classical inter-molecular O-H⋯O hydrogen bonds, forming centrosymmetric dimers.
متن کامل5-Methylisoxazole-4-carboxylic acid
In the title compound, C(5)H(5)NO(3), the mol-ecule lies on a crystallographic mirror plane with one half-mol-ecule in the asymmetric unit. An intramolecular C-H⋯O inter-action is present. In the crystal, strong inter-molecular O-H⋯N hydrogen bonds result in the formation of a linear chain structure along [100], and there are also weak C-H⋯O hydrogen bonds between the chains which help to stabi...
متن کاملInhibition of 5-oxoprolinase by 2-imidazolidone-4-carboxylic acid.
L-2-Imidazolidone-4-carboxylic acid is an effective competitive inhibitor of the reaction catalyzed by 5-oxoprolinase, in which 5-oxo-L-proline (L-pyroglutamic acid, L-2-pyrrolidone-5-carboxylic acid, L-5-oxopyrrolidine-2-carboxylic acid) is converted to L-glutamate, with concomitant cleavage of ATP to ADP and orthophosphate. L-2-Imidazolidone-4-carboxylate decreased the rate of metabolism of 5...
متن کامل1-Cyclohexyl-2-(3-furyl)-1H-benzimidazole-5-carboxylic acid
The asymmetric unit of the title compound, C(18)H(18)N(2)O(3), contains two mol-ecules. The fused rings of both mol-ecules are almost planar, with dihedral angles of 3.1 (1) and 2.8 (2)° between the fused rings. The furan rings are rotated by 43.85 (15) and -21.07 (9)° with respect to the planes of the attached bnzimidazole systems. In the crystal, mol-ecules are linked into infinite chains by ...
