An organic proton transfer compound, 2-hydroxy pyridinium 3, 5-dinitrobenzoate (HPDA)
was synthesized from 3, 5-dinitro benzoic acid and 2-hydroxy pyridine using methanol …

Two pyridoxine derivatives containing a dinitrophenyl moiety were investigated by 1H NMR
spectroscopy. Conformational dynamics in solution were studied for each compound using …

A series of pyridoxine derivatives was investigated by 1H and 2D nuclear overhauser
enhancement spectroscopy (NOESY) NMR. The free energies of activation for the pyridyl …

The conformational properties of three pyridoxine derivatives were studied by 1H dynamic
NMR spectroscopy. Conformational exchange caused by a rotation of 2‐nytrophenyl group …

The article describes a simple technique for comparative analysis of the second harmonic
generation properties of new samples and etalon materials by their powders. The …

The syntheses of a series of novel derivatives of stilbazole and their azo-analogs bearing
the phenylalkenyl and phenyldiazenyl substituents at position 6 of the pyridoxine ring are …

In the last decade, pyridoxine derivatives were widely used for the synthesis of molecules
with important biological and physical properties. However, rational synthesis of the …
