Intense Activity

In recent years, visible-light-mediated copper photocatalysis have emerged as an attractive strategy for the diverse constructions of basic bonds in an ecologically benign and cost-effective fashion. The intense activity and increasing work of these areas stimulated the exploit of the distinctive properties of copper photocatalysis and the rapid development and expansion of their applications. In this review, we focus on introducing a series of significant achievements in copper complexes as standalone photocatalysis in organic reactions to make an attempt to exhibit their potential capabilities and high flexibilities in synthetic chemistry.

Decarboxylative Coupling

The selective modification of α-amino acids and peptides constitutes a pivotal arena for accessing new peptide-based materials and therapeutics. In recent years, visible light photoredox catalysis has appeared as a powerful platform for the activation of small molecules via single-electron transfer events, allowing previously inaccessible reaction pathways to be explored. This review outlines the recent advances, mechanistic underpinnings, and opportunities of applying photoredox catalysis to the expansion of the synthetic repertoire for the modification of specific amino acid residues.1 Introduction2 Visible-Light-Mediated Functionalization of α-Amino Acids2.1 Decarboxylative Functionalization Involving Redox-Active Esters2.2 Direct Decarboxylative Coupling Strategies2.3 Hypervalent Iodine Reagents2.4 Dual Photoredox and Transition-Metal Catalysis2.5 Amination and Deamination Strategies3 Photoinduced Peptide Diversification3.1 Gese-Type Bioconjugation Methods3.2 Peptide Macrocyclization through Photoredox Catalysis3.3 Biomolecule Conjugation through Arylation3.4 C–H Functionalization Manifolds4 Conclusions and Outlook
