Reactions of Pyridoxal with Heterocycles Containing Primary Amino Group

Abstract

© 2018, Pleiades Publishing, Ltd. New nitrogen-containing derivatives of pyridoxal were obtained as a result of its reaction with various amines. The reactions with amines bearing a heterocyclic fragment (pyridine, pyrimidine, quinoline, piperidine) furnished the final products stabilized in an aminoacetal form. The product prepared from 2-aminomethylpiperidine has an imidazolidine fragment in the molecule
