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 ...

In the crystal structure of the title compound, C(10)H(8)N(2)O(3)·H(2)O, mol-ecules are linked via inter-molecular O-H⋯O and O-H⋯N hydrogen bonds into a two-dimensional network.
متن کاملl-2-Nitrimino-1,3-diazepane-4-carboxylic acid monohydrate
The cyclic form of l-nitro-arginine, C(6)H(10)N(4)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. According to the geometrical parameters, similar in both mol-ecules, the structure corresponds to that of l-2-nitrimino-1,3-diazepane-4-carboxylic acid; there are, however, conformational differences between the independent molecules, one of them being close to a twisted ...
متن کاملSYNTHESIS 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...
متن کامل(2S,3S)-3-(4-Chlorophenyl)-8-methyltropane-2-carboxylic acid
In the title compound, C(15)H(18)ClNO(2), the inter-nal torsion angles of the tropane ring are comparable to those of tropane rings in the crystal structures reported for cocaine and its derivatives. There is an intra-molecular hydrogen bond between the N atom in the tropane ring and the O atom of the carboxyl group. The crystal structure is further stabilized by many weak C-H⋯O inter-actions b...
