O-alkyl-N-acylphosphoramido(thio)(seleno)ates. Their structures were confirmed by MS analysis and 1H and 31P NMR spectroscopy. Independently N-acylphosphoramidoselenoates were converted to N-acylphosphoramidates by treatment with tert-butylperoxytrimethylsilane. The oxathiaphospholane approach was also applied to the synthesis of derivatives having N-prolylphosphoramido(thio)(seleno)ate linkages on the 5′-OH
制备了羧酰胺的N- [2-(X)-1,3,2-氧代磷杂环戊烷]衍生物(X = S,Se,O),它们与醇的DBU辅助反应生成了相应的O-烷基-N-酰基磷酰胺基(硫代)(硒代)酸酯 通过MS分析,1 H和31 P NMR光谱确认了它们的结构。通过用叔丁基过氧三甲基硅烷处理,独立地将N-酰基磷酰胺基磺酸酯转化为N-酰基磷酰胺基酸酯。氧杂磷腈方法也被用于合成在AMP的5'-OH基团上具有N-脯氨酰磷酰胺基(硫代)(硒代)酸酯键的衍生物。
