Abstract: Abstract A series of novel 5-(4-substituted phenylazo)-1-carboxymethyl-3-cyano-6-hydroxy-4-methyl-2-pyridones had been synthesized and characterized. The study includes spectral determination of the possible tautomeric forms and the intramolecular hydrogen bonding pattern. The influence of the bifurcated intramolecular hydrogen… read more here.
