Phosphorylation of aminomethylated derivatives of 2,7-dihydroxynaphthalenes

Phosphorylation of 2,7-dihydroxynaphthalene derivatives, containing different amine components was performed by full amides of phosphorous acid. A substantial effect of the intramolecular hydrogen bond on the process of phosphorylation was shown. Cyclophosphorylation was performed and principal possibility of the synthesis of naphthophosphacrownaphanes having aminomethyl linkers was shown. Mannich aminomethylation of naphthophosphacyclophanes was found to be impossible.
