nucleosidic phosphoramidite blocks were synthesized by a Mitsunobu reaction between 2'-deoxy-5'-O-(4,4'-dimethoxytrityl)uridine and a primary alcohol containing a conjugate group in its structure (a protected functional group, an organic dye, or a precursor of a lanthanide(III) chelate) followed by phosphitylation. They were used in machine-assisted DNA synthesis in the standard manner. A slightly modified deprotection
[反应:见正文]通过2'-脱氧-5'-O-(4,4'-二甲氧基三苯甲基)尿苷与结构中含有共轭基团的伯醇之间的Mitsunobu反应合成了新型核苷亚磷酰胺嵌段(官能团,有机染料或镧系元素(III)螯合物的前体),然后进行磷酸化。它们以标准方式用于机器辅助DNA合成。略加修饰的脱保护程序用于制备拴在镧系元素(III)螯合物上的寡核苷酸缀合物。对于后一种应用,还合成了一个非核苷嵌段。
