allows facile macrocyclization of peptides in the N‐to‐C direction. Combined with the previously developed β‐C(sp3)−H arylation method for peptide macrocyclization in the C‐to‐N direction, a pair of palladium‐catalyzed reactions were obtained that are directionally orthogonal, and the first example of one‐pot synthesis of bicyclic peptides via Pd‐catalyzed β‐C(sp3)−H and δ‐C(sp2)−H activation is demonstrated
