Synthesis: [1]


Comment: Alternate symbol is cmam5Um. The natural nucleoside from E. coli tRNALeu was originally characterized by comparison of its NMR spectrum with that of synthetic material [1]. The discovery of cmnm5Um is cited in [1] as a meeting abstract [2], in which, however, the compound is neither named nor structural data presented. A recent and more rigorous structural characterization is reported in [3].
