摘要: 具有生物活性的 α-氨基烃基膦酸的合成有过报道[1], 而氮烃基-α-氨基烃基膦酸的合成报道较少. 应用醛、苄胺与亚磷酸酯反应后在强酸条件下水解得到取代的 α-氨基烃基膦酸[2, 3].IssIeib用三甲基硅基膦酸与席夫碱加成然后再水解[4]. 这些方法尽管得到相应的膦酸产物,但它的水解却需要较长时间。

Abstract: Some N-alkyl-α-aminobenzylenephosphonic acids were prepared directly from benzaldehyde or p-nitrobenzaldehyde with amines and phosphorous acid using tetramethylenesulfone as solvent. The method offers the advantages of giving good yields, easy purification of the products, simplicity and rapidity.

Key words: N-alkyl-α-aminobenzylenephosphonic acid, tetramethylenesulfone, synthesis
