Unique taurine-containing uridine derivatives, 5-taurinomethyluridine (τm5U) and 5-taurinomethyl-2-thiouridine (τm 5S2U), which were discovered in mammalian mitochondrial tRNAs, exist at the first position of the anticodon. In this paper, we report the first efficient synthesis of τm5U and τm 5S2U and describe their physicochemical properties. These modified ribonucleosides were synthesized by the reaction of 5-substituted uridine derivatives with a tetrabutylammonium salt of taurine that is highly reactive and wellsoluble in common organic solvents. UV and 1H NMR spectrometric studies revealed the structural properties of the taurine-containing base moieties and the sugar conformations of these modified ribonucleosides.
