2-Amino- and 2-alkylthio-4H-3,1-benzothiazin-4-ones: synthesis, interconversion and enzyme inhibitory activities.
The synthetic access to 2-sec-amino-4H-3,1-benzothiazin-4-ones 2 was explored. Compounds 2 were available from methyl 2-thioureidobenzoates 1, 2-thioureidobenzoic acids 3, and novel 2-thioureidobenzamides 6, respectively, under different conditions. 2-Alkylthio-4H-3,1-benzothiazin-4-ones 5 have been prepared from anthranilic acid following a two step route. Both, benzothiazinones 2 and 5 underw...
متن کامل4-(2,4-Dichlorophenyl)-2-(1H-indol-3-yl)-6-(2-pyridyl)-1,4-dihydropyridine-4-carbonitrile
The title compound, C(25)H(16)Cl(2)N(4), has intra-molecular N-H⋯N and C-H⋯Cl hydrogen bonds. In the crystal structure, mol-ecules are linked through N-H⋯N hydrogen bonds, forming a centrosymmetric R(2) (2)(16) dimer.
متن کامل2-Amino-6-methylpyridinium 4-methylbenzenesulfonate
In the asymmetric unit of the title salt, C6H9N2 (+)·C7H7O3S(-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent 4-methyl-benzene-sulfonate anions. Both cations are protonated at their pyridine N atoms and their geometries reveal amine-imine tautomerism. In the 4-methyl-benzene-sulfonate anions, the carboxyl-ate groups are twisted out of the benzene ring planes...
متن کامل2-Amino-6-methylpyridinium 4-hydroxybenzoate
In the title mol-ecular salt, C6H9N2 (+)·C7H5O3 (-), the dihedral angle between the benzene ring and the CO2 group in the anion is 6.1 (2)°. In the crystal, the cation and anion are linked by N-H⋯O and C-H⋯O hydrogen bonds, and the anions are connected by O-H⋯O hydrogen bonds, forming a three-dimensional network.
متن کاملSynthesis and in vitro Antibacterial Activity of Some Novel 2-Amino-4, 6-D Derivatives
Heterocyclic systems are one of the most important classes of organic compounds present in nature or synthesized in laboratory. These compounds posses an array of biological activities and are employed in the treatment of commonly occurring diseases. Keeping this in view, some new 2-amino-4,6-diarylpyrimidine from chalcones were synthesized. Eight novel 2-amino-4,6-diarylpyrimidine derivatives ...
