Abstract
2â²-O-aminopropyl modified 4,6-difluoro-substituted benzimidazole nucleosides were synthesized in a two-step synthesis via Michael reaction and a Raney-nickel catalyzed reduction in high yields. These building blocks were used as a starting point for the conjugation of different carboxylic acids to enhance the lipophilicity or cationic character of oligonucleotides when used in biological assays or medical applications.
