á-Amino phosphonates, due to their structural analogy to á-amino acids, have been the subject of considerable current interest. A number of synthetic methods have been reported for the synthesis of á-amino phosphonates during past few decades. Of these methods, the nucleophilic addition of phosphites to imines, catalyzed by a base or an acid, is the most convenient. The catalytic activity of a series of bismuth salts has been studied. Our bismuth salts-induced procedure has notable advantages that include simple operation, environment friendly conditions, faster reactions and high yields of products. |
