Abstract

The synthesis of DNA oligomers containing N4-hydroxy-5,6-dihydrocytosine-6-sulfonate by using ligand-induced base flipping of cytosine followed by the simultaneous addition of bisulfite and hydroxylamine is reported. In contrast to C, the flipped-out 5-methylcytosine was selectively oxidized over thymines and cytosines in the duplex by potassium permanganate. Ligand-induced base flipping is a convenient and powerful strategy for the synthesis of modified cytosines and 5-methylcytosines related to bisulfite sequencing at the predetermined site of DNA.
