Abstract


Pyridoxal monoimines were obtained by the reaction of pyridoxal with aromatic diamines. A change in the ratio of the reagents or introduction of another aromatic aldehyde into the reaction leads to the formation of symmetric and asymmetric diimines. In some cases, the initially formed diimines are transformed into the corresponding benzimidazoles. The products of the reaction of pyridoxal with 1,3-diaminobenzene have a furopyridine structure.

Keywords
