Cytosine has been readily alkylated with trialkylphosphates to give the corresponding N-alkyl derivatives, trimethyl phosphate being especially useful for the N-methylation of the base moiety of cytosine nucleosides.

but strongly mutagenic DNA base adduct; however, the sequencing method to determine m3T is lacking so far. Two of the main obstacles include the capacity of m3T to stall DNA elongation and its low abundance. To address the challenges, we report an unnatural base pairing strategy in this paper. A new m3T–TPT3 base pair was developed with a Vmax/Km value 82-fold higher than that of the m3T-A pair. The
