A set of nicotinic acid derived tetrazines were synthesized and evaluated for activity in inverse-electron-demand Diels-Alder (IEDDAA) reactions with various dienophiles. It was found that the performance of these tetrazines is governed by two factors. Theoretical and experimental investigations showed that steric effects may override the energetically predicted order of reactivity. Making a compromise between reactivity and stability, a selected tetrazine was incorporated into a deoxynucleotide to afford a bioorthogonalized building block enabling IEDDA-based tagging schemes of nucleic acids.
