Modification reaction conditions: KHCO3 (20 mM), 5′-TTTTT-3′-alkyl-NH2 (0.2 mM), azide derivatives 1b–1j (7.5 mM), and PPh3 (20 mM) in BMPy OTf at 50 °C for 2 h. *Reaction was incubated overnight. Conversion in the parentheses were calculated based on matrix-assisted laser desorption/ionization (MALDI-MS) analysis. Conversion obtained by liquid chromatography is available in Fig. S2.

    1. The peak observed at ∼302 ppm turned out to be a sideband artifact approximately 7813 Hz from an intense solvent peak. These artifacts appeared consistently when the direct 15N detection was performed on the triple-resonance inverse cryoprobe used in the study, and there have been unusually strong signals. On the other hand, when indirect methods (e.g. HMBC experiment), such strong peaks were not observed
