BODIPY Peptide Labeling by Late‐Stage C(sp³)−H Activation

Abstract

Abstract Late‐stage BODIPY diversification of structurally complex amino acids and peptides was accomplished by racemization‐free palladium‐catalyzed C(sp 3 )−H activation. Transformative fluorescence modification proved viable by triazole‐assisted C(sp 3 )−H arylation in a chemo‐ and site‐selective fashion, providing modular access to novel BODIPY peptide sensors.
