order to obtain esters of (p-ethoxycarbonylphenylaminomethyl)phosphonic acid. Three compounds were synthesized and their toxic and radioprotectant properties examined. As is well known, the phosphonomethylation of amines can be effected by reacting them with paraformaldehyde and trialkyl phosphites [2, 3, 6], or by the Kabachnik--Fields reaction with paraformaldehyde and dialkyl phosphites [5, 12]. It
我们现在第一次使用膦酰基甲基化麻醉剂以获得(对乙氧基羰基苯基氨基甲基)膦酸的酯。合成了三种化合物并检查了它们的毒性和辐射防护特性。众所周知,胺的膦酰基甲基化可以通过将它们与多聚甲醛和亚磷酸三烷基酯反应 [2, 3, 6],或通过与多聚甲醛和亚磷酸二烷基酯的 Kabachnik--Fields 反应来实现 [5, 12]。还已知第一个系统优选用于对氨基苯酚和对苯胺 [4] 的膦酰甲基化。
