We recently reported the use of PSCl3 for the thiophosphorylation of alkylamines where the resulting N-thiophosphoramidate ions could be readily S-alkylated (Chem. Commun., 2011, 47, 6156–6158.). Herein we report the development of this methodology using amino acid, amino sugar, aminonucleoside and aniline substrates. The hydrolysis properties of N-thiophosphoramidate ions and their reactivities towards alkylating agents are also explored. In addition, we demonstrate the application of our approach to the preparation of a small library of compounds, including quinoline-based N,S-dialkylthiophosphoramidates which were tested for antileishmanial activity.
我们最近报道了使用PSCl3对烷基胺进行硫代膦酰化反应,得到的N-硫代膦酰胺离子可以容易地进行S-烷基化(《化学通讯》,2011年,第47卷,第6156-6158页)。在此,我们报道了利用氨基酸、氨基糖、氨基核苷和苯胺底物开发这种方法。研究了N-硫代膦酰胺离子的水解性质及其对烷基化剂的反应活性。此外,我们还展示了该方法在制备小规模化合物库中的应用,其中包括了用于抗利什曼活性测试的喹啉基N,S-二烷基硫代膦酰胺。
