Pyridoxal Reactions with Amines and Aliphatic Diamines

摘要

Interaction of pyridoxal (3-hydroxy-5-hydroxymethyl-2-methylisonicotinaldehyde) with amines, mono- and disubstituted diamines led to the formation of compounds having in their structure imine, imidazolidine, and pyrimidine moieties. Structure of the obtained compounds was proved by IR data, H-1 NMR spectroscopy, mass spectrometry, and X-ray diffraction analysis.
