Late-Stage Peptide Diversification by Position-Selective C-H Activation

Abstract

The late-stage modification of structurally complex peptides bears great potential for drug discovery, crop protection, and the pharmaceutical industry, among others. Whereas traditional approaches largely rely on prefunctionalizations, C-H activation catalysis has in recent years emerged as an increasingly powerful tool for post-translational peptide modifications in a step-economic manner. Herein, we summarize recent progress in organometallic C-H activation on peptides until June 2018, including position- and chemoselective palladium-, ruthenium-, and manganese-catalyzed processes.

Keywords: C−H activation; amino acids; peptides; transition metals.
