scheme or table, p. 594 - 598 (2012/01/05)
A new approach to asymmetric synthesis of γ-aminophosphonic acids is described. It involves the diastereoselective addition of various carbon and phosphorus nucleophiles to enantiopure (+)-(S)-N-[(3-diethoxyphosphoryl) propylidene]-p-toluenesulfinamide an

The syntheses of 1-aminoalkane-1,n-diphosphonic acids (n=2-4) by the thioureidoalkanephosphonate method are described.The acidities of these amino acids were determined potentiometrically.Key words: Phosphorus; Phosphonic acid; Aminoalkanephosphonic acids

ω-Phosphonocarbonyl compounds and dicarbonylcompounds react with benzhydrylamine to the corresponding Schiff bases.The latter add diethylphosphite under formation of N-benzhydryl-alkyl-tetraalkyl-phosphonates.Acidolysis with concentrated hydrobromic acid and following treatment with epoxide or ion exchanger gives the title compounds in high yields.The bahavior of aminophosphonic acids under transamination conditions against different substrates and with variable metal ions as catalysts has been investigated.
