报告摘要:
Peptide macrocycles have emerged as a powerful platform for drug discovery, especially for biological targets that are difficult to modulate by conventional small molecule drugs. To realize the full potential of this platform, new strategies are needed to streamline the synthesis of peptide macrocycles with novel structures. We will discuss 1) exploration of palladium-catalyzed C−H functionalization strategy for total synthesis of complex peptide natural products and construction of cyclophane-braced peptide macrocycles; 2) a metal-free cooperative stapling method of native peptides at lysine and tyrosine or arginine with formaldehyde; 3) a recent development of Pd-catalyzed intramolecular S-Arylation reaction to assemble complex peptide structures for synthesis and biological screening of DNA-encoded library.
