A versatile method for the construction of C(sp)-linked cyclophane peptide macrocycles via Pd-catalyzed picolinamide-directed intramolecular arylation of aryl and alkenyl C-H bonds of amino acid side chains with aryl iodides is developed. This method provides simple and efficient access to a variety of cyclophane-braced structures from readily accessible linear peptide precursors.
