A large number of new lipophilic mono- and bisphosphinylamines including those possessing additional potential centers of coordination was synthesized on the basis of the Kabachnik-Fields reaction, and acid-base and membrane transport properties of the synthesized compounds toward the mono- and polybasic carboxylic acids were studied. By their basicity all the synthesized aminophosphine oxides were
在Kabachnik-Fields反应的基础上,合成了许多新的亲脂性单膦酸和双膦胺,包括具有额外潜在配位中心的那些,以及合成的化合物对一元和多元羧酸的酸碱和膜传输特性被研究了。由于它们的碱性,所有合成的氨基膦氧化物均显示出劣于其脂族胺前体。第二次膦基的引入极大地降低了碱性,以致于不可能通过电位法确定p K a。讨论了氨基次膦酰基载体与底物的结构与酸性底物的膜运输效率之间的相互关系。

alpha-Aminophosphoryl compounds of the phosphonate, phosphine oxide, and alpha,omega-bis(phosphine oxide) series and some of their thiophosphoryl analogs were synthesized. Potentiometric measurements of the pK(a) of the conjugate acids revealed an insignificant effect of variation of substituents on the phosphorus, nitrogen, and alpha-carbon atoms on the basicity of the phosphorylated amines. The latter are weak bases. Organophosphorus groups decrease the basicity of the amines by almost 5 pK(a) units. The role of the hydrophobic effect and intramolecular H-bonding in the obtained substances was discussed.
