ABSTRACT
Amino-containing derivatives of various structures have been obtained via Mannich reaction in a series of bicyclic phosphonates based on 2-methylresorcinol, resorcinol, and pyrogallol with paraformaldehyde and secondary amines via Mannich reaction. The structure and composition of the obtained compounds have been determined using 31P and 1H NMR spectroscopy, IR spectroscopy, mass spectrometry (MALDI-TOF), and X-ray analysis.
