The phosphorus-substituted amides of carboxylic acids are of great interest as effective ligands and biologically active substances of different action [1]. Recently we suggested convenient methods of synthesis of various phosphorus-substituted amides of carboxylic acids including those containing fragments of 2,6-di-tert-butylphenol on the basis of easily available N-chloroamides and trimethylsilyl
羧酸的磷取代酰胺作为有效的配体和不同作用的生物活性物质引起了人们的极大兴趣[1]。最近,我们提出了合成各种磷取代的羧酸酰胺的简便方法,包括在容易获得的 N-氯酰胺和三价磷酸的三甲基甲硅烷酯的基础上含有 2,6-二叔丁基苯酚片段的那些 [2] . 在这项工作中,容易获得的异和对苯二甲酰氯 [3] 可以很容易地添加到二氯甲烷介质中的不同亚胺中,得到中间体 -(参见 [4]),它在温和条件下与过量的磷酸二乙酯(三甲基甲硅烷基)顺利反应,以高产率生产二磷取代的双酰胺 I-VIII。DOI: 10.1134/S1070363210010263
