Synthesis of<i>N,N</i>-Bis(dialkoxyphosphinoylmethyl)- and<i>N,N</i>-Bis(diphenylphosphinoylmethyl)-β- and γ-amino acid Derivatives by the Microwave-Assisted Double Kabachnik-Fields Reaction
The title compounds were synthesized by the microwave-assisted, mostly solvent-free bis Kabachnik–Fields condensation of β-alanine and γ-aminobutyric acid or their esters with formaldehyde and >P(O)H species, such as dialkyl phosphites and diphenylphosphine oxide.

derivatives of trivalent organophosphorus acids, containing PH and POSiMe3 fragments with various bis- and tris(alkoxymethyl)amines and bis(alkoxymethyl)amino acids, is proposed as a convenient method for the synthesis of new bis- and trisphosphorylated amines and amino acids as well as their derivatives with four and five coordinated phosphorus. Also the three-components systems of phosphorous acid, paraformaldehyde
