| Popis: | A simple, efficient and eco-friendly protocol has been described for the synthesis of α-aminophosphonates via Kabachnik-Fields reaction, catalyzed by H6P2W18O62·14H2O as a reusable catalyst. The reaction was realized by condensation of amino acids, various aromatic aldehydes and triethylphosphite under solvent-free conditions, the corresponding α-aminophosphonates were formed in good yields. All the new products were characterized by IR, 1H, 13C and 31P-NMR analyses. This method offers advantages such as simplicity workup with the green aspects, good yields and short reaction times. |
