Chemoenzymatic tandem cyclization for the facile synthesis of bicyclic peptides

Communications Chemistry
Bicyclic peptides exhibit improved metabolic stabilities and target specificities when compared to their linear or mono-cyclic counterparts; however, efficient and straightforward synthesis remains challenging due to their intricate architectures.

The Copper-Catalyzed Azide-Alkyne Cycloaddition Reaction: Why Two Is Faster than One. [PDF]

Chemphyschem
Quantum chemical analyses uncover that the copper‐catalyzed azide–alkyne cycloaddition favors the dinuclear catalyst mechanism over the mononuclear analog due to reduced steric Pauli repulsion between the copper acetylide and the azide, rather than relief of strain in the six‐membered metallacycle. The copper‐catalyzed azide–alkyne cycloaddition (CuAAC)
