Incorporation of modified nucleosides with a flexible universal linker is of great value for post-synthetic modification of nucleic acids. Thus, C8-alkynyl- and alkylamino substituted 2′-deoxyguanosines were synthesized for the first time and incorporated into short oligonucleotide sequences. The preference for syn conformation of these C8-substituted 2′-deoxyguanosines and the stability of the duplexes
修饰的核苷与柔性通用接头的结合对于核酸的合成后修饰具有巨大的价值。因此,首次合成了C8-炔基-和烷基氨基取代的2'-脱氧鸟苷,并将其掺入短的寡核苷酸序列中。讨论了这些C8取代的2'-脱氧鸟苷的顺式构象的偏爱性和双链体的稳定性。还检查了Z-DNA的稳定作用。
