A palladium-catalyzed Negishi coupling reaction has been developed to synthesize fluorous 5-methylcytosines. These fluorous nucleosides are incorporated into the oligonucleotides that correspond to part of the promoter region of Oct4, a master gene that undergoes dynamic DNA demethylation during cellular reprogramming. The separation of the fluorous oligonucleotides from its nonfluorous analogues has been achieved through solid-phase extraction over fluorous silica, suggesting its potential use in probing DNA demethylation.
