    Proximity-induced methodologies for peptide and protein modification have been developed using recognition elements like inhibitors, antibodies, or affinity tags on amino acids. However, the recognition a of saccharides for chemical modification remains widely unexplored. Recent studies exploring boronic acids and their derivatives have shown their alluring capabilities as selective molecular recognition elements for saccharides, providing the first insight into a recognition methodology for this moiety. Herein is described the discovery of catalytic proximity-induced rhodium(II) methodology for covalent modification of glycopeptides using boronic acids as a saccharide recognition element.

    Light is a uniquely powerful tool for spatiotemporal control of molecular structure, necessitating the development of new photocaging approaches. This communication describes the design, synthesis, and reactivity of two new photoreactive boronic acid reagents for backbone N–H modification and subsequent photocleavage.
