Seven phosphane-functionalized deoxyuridines have been prepared by amidebondformation between aminodeoxyuridines and phosphanylcarboxylic acids. X-ray crystal structures for two of these new modified nucleosides have been obtained. The same coupling method has been extended to oligonucleotides. The phosphane containing strands have been purified and characterized by MALDI-TOF and, for the first time
已经通过氨基脱氧尿苷和膦酰羧酸之间的酰胺键形成制备了七种磷烷官能化脱氧尿苷。已经获得了这些新修饰核苷中的两个的 X 射线晶体结构。相同的偶联方法已扩展到寡核苷酸。含磷烷的链已通过 MALDI-TOF 和首次 31 P NMR 光谱法纯化和表征。磷烷修饰的 15 聚体与 [PdCl(η 3 -烯丙基)] 部分的配位已通过 31 P NMR 光谱证实。
