Our results suggest that fluorination at the 2'-B or 2'-A,B positions somewhat stabilizes in vacuo the AI relative to the BI conformations. In contrast, substitution of the CF2 group for the O4' atom (O4'-CF2 modification) leads to a preference of the BI relative to AI DNA-like conformers. All the studied modifications result in a noticeable increase in the stability of the glycosidic bond [estimated by the relaxed force constants (RFC) approach], with particularly encouraging results for the O4'-CF2 derivative. Consequently, the O4'-CF2 modified systems are suggested and explored as promising scaffolds for the development of duplex and quadruplex structures with reduced propensity to form abasic lesions and to undergo DNA damage.
