In aqueous solution ω-formylalkylphosphonates in the presence of hydrogen cyanide and (S) (-) α-methylbenzylamine give optically active aminonitriles with an enantiomeric excess of 50percent.Phosphonic aminonitriles are submitted to acid hydrolysis, then esterified and debenzylated without any epimerization.The separation is performed either with the acid or with the ester.All the operations are monitored by NMR (1H, 13C, 31P) and whenever possible, by GC.
