Tanpure, A., & Balasubramanian, S. (2017). Synthesis and Multiple Incorporations of 2′-O-Methyl-5-hydroxymethylcytidine, 5-Hydroxymethylcytidine and 5-Formylcytidine Monomers into RNA Oligonucleotides. ChemBioChem https://doi.org/10.1002/cbic.201700492
The synthesis of 2′-O-methyl-5-hydroxymethylcytidine (hm5Cm), 5-hydroxymethylcytidine (hm5C) and 5-formylcytidine (f5C) phosphoramidite monomers has been developed. Optimisation of mild post-synthetic deprotection conditions enabled the synthesis of RNA containing all four naturally occurring cytosine modifications (hm5Cm, hm5C, f5C plus 5-methylcytosine). Given the considerable interest in RNA modifications and epitranscriptomics, the availability of synthetic monomers and RNAs containing these modifications will be valuable for elucidating their biological function(s).
