Synthesis of 4-Pyridone-3-sulfate and an improved synthesis of 3-Hydroxy-4-Pyridone
An improved synthesis of 3-hydroxy-4-pyridone via an Elbs oxidation of 4-pyridone and isolation of 4-pyridone-3-sulfate is described.
متن کامل2-Ethyl-3-hydroxy-1-isopropyl-4-pyridone
The title compound, C(10)H(15)NO(2), crystallized with three mol-ecules in the asymmetric unit. These three mol-ecules are quite similar except for slight differences in the torsion angles of the substituents on the ring. The isopropyl C-C-N-C torsion angles (towards the carbon next to the ethyl bound carbon), for example, are -150.63 (11), -126.77 (13) and -138.76 (11)° for mol-ecules A, B and...
متن کاملCrystal structures of three hydrogen-bonded 1:2 compounds of chloranilic acid with 2-pyridone, 3-hydroxypyridine and 4-hyroxypyridine
The crystal structures of the 1:2 compounds of chloranilic acid (systematic name: 2,5-di-chloro-3,6-dihy-droxy-1,4-benzo-quinone) with 2-pyridone, 3-hy-droxy-pyridine and 4-hyroxypyridine, namely, bis-(2-pyridone) chloranilic acid, 2C5H5NO·C6H2Cl2O4, (I), bis-(3-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (II), and bis-(4-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (III), ...
متن کاملThe peculiar binding properties of 4'-deoxy,4'-iododoxorubicin to isolated DNA and 175 bp nucleosomes.
The thermodynamic parameters governing the interaction of 4'-deoxy,4'-iododoxorubicin (4'-IAM) to double stranded DNA or 175 bp nucleosomes have been evaluated at different ionic strength and temperature conditions by means of fluorescence techniques. The iodo-anthracycline exhibits quite different characteristics from the parent compounds adriamycin (AM) and daunomycin (DM) and other second ge...
متن کاملTwo dialkylammonium salts of 2-amino-4-nitrobenzoic acid: crystal structures and Hirshfeld surface analysis
The crystal structures of two ammonium salts of 2-amino-4-nitro-benzoic acid are described, namely di-methyl-aza-nium 2-amino-4-nitro-benzoate, C2H8N+·C7H5N2O4-, (I), and di-butyl-aza-nium 2-amino-4-nitro-benzoate, C8H20N+·C7H5N2O4-, (II). The asymmetric unit of (I) comprises a single cation and a single anion. In the anion, small twists are noted for the carboxyl-ate and nitro groups from the ...
