ω-Formylalkylphosphonates by acid hydrolysis of the corresponding acetals obtained from triethylphosphite and bromoacetals has been described. In aqueous solution in the presence of cyanide and amines these compounds give aminonitriles (Strecker) or hydantoins (Bucherer). These reactions give access to a large variety of compounds which by acid hydrolysis (Strecker) or basic then acid hydrolysis (Bucherer)
已经描述了通过酸水解由亚磷酸三乙酯和溴缩醛得到的相应缩醛的ω-甲酰基烷基膦酸酯。在氰化物和胺存在下的水溶液中,这些化合物会生成氨基腈(Strecker)或乙内酰脲(Bucherer)。这些反应提供了多种化合物,这些化合物通过酸水解(Strecker)或碱性然后酸水解(Bucherer)生成纯的氨基羧基烷基膦酸(膦酰丙氨酸等)。
