Synthesis of new diarylmethanes on the basis of resorcinol derivatives and amino acetals containing an aminoethylidenebisphosphonate fragment

详细

New ethylenebisphosphorylated α-amino acetals were synthesized by the reaction of aminoacetaldehyde dimethyl acetal with ethenylidenebisphosphonates (Michael reaction). It was found that the synthesized compounds react with 2-methylresorcinol and resorcinol in the presence of HCl to form previously unknown diarylalkylammonium salts containing ethylidenebisphosphonate groups.
