The reaction of equimolar amounts of pyridoxal and 1,2-propylenediamine leads to the formation of monoimine, which exists as a cyclic imidazolidine tautomer. The latter reacts with aromatic aldehydes to form unsymmetric bisazomethines. The reaction o

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.
