Methionine-Facilitated Chalcogenation of Peptides through Palladium-Catalyzed β-C(sp3)-H Activation

Abstract

We report a novel methodology for the site-selective chalcogenation of peptides via Pd-catalyzed β-C(sp3)-H activation. In this study, native methionine residues serve as an intrinsic directing group, while various diaryl disulfides/diselenides act as coupling parterner, affording chalcogenated peptides in moderate to good isolated yields.
