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 ...

The title compound, C(11)H(9)N(3)OS, was prepared to investigate the coordination chemistry of thio-phene-containing ligands as precursors to inter-esting metallopolymers. The mol-ecule is nearly planar. The angle between the thio-phene and pyridine rings is 8.63 (4)° and features the expected trans configuration about the imine bond. The structure is stabilized by a weak inter-molecular N-H⋯O ...

The present research describes the synthesis of novel 5-benzoyl-N-substituted-amino- and 5-benzoyl-N-sulfonylamino-4-alkylsulfanyl-2-pyridones 5a-c and 6a-c via the reaction of 2-benzoyl-3,3-bis(alkylthio)acrylonitriles 2a-c with N-cyanoacetohydrazide 3 and cyanoaceto-N-phenylsulfonylhydrazide 4, respectively. Also, the reactivity of the compounds 5a-c toward hydrazine hydrate to give product 1...

reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded n?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave n?, n?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. treatment of 3 with sodium hydroxide afforded 2h[n-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. cyc...
