5-Carboxymethylaminomethyluridine (cmnm5U) and 5-carboxymethylaminomethyl-2-thiouridine (cmnm5s2U) are located at the wobble position in several cytosolic and mitochondrial tRNA sequences. In this paper, we report the first site-selected incorporation of cmnm5U and cmnm5s2U into RNA sequences by phosphoramidite chemistry on a CPG solid support. Trifluoroacetyl and 2-(trimethylsilyl)ethyl were selected for the protection of the amine and carboxyl functions, respectively.
