1,2,3-Triazoles are important structural motifs in diverse research fields, ranging from medicinal chemistry and agriculture to materials science.1

These heterocycles have proved very valuable as isostere of the amide group in bioactive molecules on account of their remarkable metabolic stability.2 While 1,2,3-triazoles are not present in naturally occurring compounds, the “amide-triazole bioequivalence” was exploited for  development of, among others, HIV-1 protease inhibitor 13 and a potential anticancer agent 24 (Figure 1). Moreover, the 1,2,3-triazole unit is already present in three commercialized drugs (e.g.Tazobactam 3 in Fig. 1).5 The fragment 1,2,3-triazole is also intensively used in peptidomimetics.6

Technological applications of 1,2,3-triazoles include photostabilizing agents for polymers, whitening agents for thermoplastic resins (e.g., compound in Figure 1)  and corrosion inhibitors.7 Noteworthy, the recent advent of click-chemistry has resulted in novel 1,2,3-triazole-based materials such as linear polymers,8 dendrimers,9  and ionic liquids.10
