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) .

The exo-stereoisomer bicyclononine in exo-BCN CE-phosphoramidite exhibits a cycloaddition rate that does not differ significantly from its endo-conformer, indicating that the choice of isomer is not critical for application.

Oligo synthesis details

Diluent:	dry acetonitrile
Coupling conditions:	coupling time 6 minutes. Oxidation: 0.5M (1S)-(+)-(10-camphorsulfonyl)-oxaziridine (CSO) in dry acetonitrile, 2 minutes. The modification is incompatible with iodine oxidation. Exclude the dimethoxytrityl (DMT) removal step (as in DMT-on protocol), because the modification is acid sensitive.
Deprotection conditions:	AMA (40% aq. methylamine, 25% ammonia, 1:1 mixture), 2 hours, room temperature
