Further investigation of the synthesis of deoxyribonucleoside-3' (t-butyl) O-(2-cyanoethyl) phosphorothioites as monomer building units for the phosphorothioite approach has led us to conclude that internucleotidic bond formation proceeded via bis(deoxyribonucleoside-3') (2-cyanoethyl) phosphite intermediates, which proved to be activated by iodine, rather than the mechanism previously reported. In connection with this study, deoxyribonucleoside-3' dimethyl phosphites were synthesized and detailed properties of them are also described.
对作为亚磷硫酯法单体构建单元的脱氧核糖核苷-3'(叔丁基)O-(2-氰基乙基)亚磷硫酯合成的进一步研究使我们得出结论,核苷酸间键的形成是通过双(脱氧核糖核苷-3')(2-氰基乙基)亚磷酸酯中间体进行的,事实证明该中间体可被碘激活,而非先前报道的机制。与此研究相关,合成了脱氧核糖核苷-3' 亚磷酸二甲酯,并对其详细性质进行了描述。
