The invention herein describes a solid-phase synthetic method for preparing thiolated oligonucleotides without needing a capping step. The methods of the invention comprises repetition of a three-reaction per cycle, namely detritylation, coupling and sulfurization, without a capping step. In some embodiments, the synthetic methods of the present invention can be used for preparing an anti-sense oligonucleotide.
本发明描述了一种无需封端步骤即可制备
硫醇化寡核苷酸的固相合成方法。本发明的方法包括每个周期重复三次反应,即脱苯甲基化、偶联和
硫化,而不需要封帽步骤。在某些实施方案中,本发明的合成方法可用于制备反义寡核苷酸。
