bioorthogonal ligation reaction that proceeds fast and with high yields. An important application of the DAinv reaction is metabolic oligosaccharide engineering (MOE) which allows the visualization of glycoconjugates in livingcells. In this approach, a sugar derivative bearing a chemical reporter group is metabolically incorporated into cellular glycoconjugates and subsequently derivatized with a probe
is not enough: Terminal alkenes are used as chemical reporters and ligation partners for 1,2,4,5‐tetrazines in a Diels–Alder reaction with inverse electron demand (DARinv). Combination with strain‐promoted azide–alkyne cycloaddition (SPAAC) allows the visualization of two different glycan structures in one experiment.
