, 2008 Rapid progress in the synthetic application of benzotriazole derivatives in the last 20 years has resulted in over 1000 scientific papers on the subject. This fact is reflected in Section 5.01.7, which involves almost a half of the volume of this chapter. The section is arranged according to hybridization of the C-α atom and atomic numbers of the atoms

Enzymatic Macrocyclization of 1,2,3‐Triazole Peptide Mimetics [PDF]
Angewandte Chemie International Edition, 2016 AbstractThe macrocyclization of linear peptides is very often accompanied by significant improvements in their stability and biological activity. Many strategies are available for their chemical macrocyclization, however, enzyme‐mediated methods remain of great interest in terms of synthetic utility.

Palladium-Catalyzed C–H Arylation of 1,2,3-Triazoles
Molecules, 2016 Palladium(II) acetate, in combination with triphenylphosphine, catalyzes direct arylation of 1,4-disubstituted 1,2,3-triazoles effectively. This C–H arylation reaction provides facile access to fully substituted triazoles with well-defined regiochemistry.
