Synthesis of phosphocyclic 2,2′,7,7′-tetrahydroxydinaphthylmethane derivatives

Two types of phosphocyclic derivatives were synthesized by phosphorylation of 2,2′,7,7′-tetrahydroxydinaphthylmethane with triamidophosphites: triphosphorus containing compounds with a phosphocine ring and two acyclic diamidophosphite fragments, and tetraphosphorus-containing macrocycles with a 24-membered ring and two eight-membered phosphorus rings. It was shown that interaction of triphosphorus compounds with resorcinarene gives tetraphosphorus macrocycles.
