α-aminophosphonates bearing free hydroxyl groups in the aromatic rings. Synthesis and NMR characterization
In this paper we describe a useful synthetic procedure leading in very good yields to mono- and bis-α-aminophosphonic acid dialkylesters containing the free phenolic hydroxyl group in a strategic position of the aromatic ring in order to enhance complexat
