]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method cars dispense with columm-chromalographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.
在这种方法中,通过使用一种由式(I)所表示的新型核苷单体化合物作为合成单元来制备寡核苷酸。其中,X、R1、Y、Base、Z、Ar、R2、R3和n如权利要求1所定义。该新型核苷单体化合物是一种核苷,其碱基基团被取代了至少一个疏水基团的芳香烃环羰基或硫羰基。该方法不需要在每次反应中进行柱层析纯化,并且不仅可以在3'-方向上进行碱基延伸,还可以在5'-方向上进行碱基延伸,从而实现寡核苷酸的高效液相大规模合成。
