for the synthesis of N3'-->P5' phosphoramidate oligodeoxynucleotides is demonstrated. Described herein is the synthesis of the monomers utilized in the phosphoramidite amine-exchange process and the experimental details pertaining to this new mode of chain assembly. The phosphoramidite amine-exchange method generates coupling yields in the 92-95% range per cycle and further enables the synthesis of chimeric
展示了一种合成N3'-> P5'氨基磷酸亚氨基寡脱氧核苷酸的新方法。本文描述了亚磷酰胺交换反应中所用单体的合成以及与这种新的链组装方式有关的实验细节。亚磷酰胺交换法在每个循环中产生的偶联收率在92-95%的范围内,并且无需进行仪器修饰即可合成嵌合的氨基磷酸酯/磷酸二酯或氨基磷酸酯/硫代磷酸酯寡核苷酸。
