The invention provides new processes for synthesizing oligonucleotides that allow for deprotection of the oligonucleotide under more rapid and/or more mild conditions than existing methods.
The invention further provides a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups, as well as nucleoside synthons having such base protecting groups. The invention also provides oligonucleotides containing any of a variety of base labile functionalities and methods for using such oligonucleotides.
本发明提供了一种合成寡核苷酸的新工艺,允许在比现有方法更快和/或更温和的条件下去保护寡核苷酸。本发明还提供了一种核苷酸碱基保护基,在寡核苷酸合成条件下稳定,但可以在比现有保护基更温和的条件下去除,以及具有这种碱基保护基的核苷酸合成单体。本发明还提供了包含各种碱基不稳定性的寡核苷酸,并提供使用这种寡核苷酸的方法。
