BCN-containing phosphoramidite is added at the 5’-terminus of an oligonucleotide. BCN is reactive both to azides (strain-promoted azyde-alkyne cycloaddition, SPAAC) and tetrazines (inverse electron demand Diels-Alder reaction, IEDDA) .
Coupling time is standard, like for amidites of natural nucleosides. Exclude the dimethoxytrityl (DMT) removal step and use the Dmt-ON protocol after amidite coupling and oxidation.
Use standard conditions for deprotection and ammonia solution, or AMA mixture (ammonium hydroxide / 40% methylamine, 1:1) for 2 hours at room temperature.
