Abstract

Bioorthogonal reactions are valuable tools for the selective labeling and imaging of natural products and proteins. Here, we present the reaction between isonitriles and chlorooximes as a ligation that proceeds quickly ( k ≈ 1 M –1 s –1 ) and with high chemoselectivity in an aqueous environment. Imaging of metabolically labeled cell surface glycans underlined the tolerance of the ligation to common functional groups in cellular systems. Live-cell dual-labeling experiments revealed that the isonitrile–chlorooxime ligation is orthogonal to the strain-promoted azide–alkyne cycloaddition.
