Abstract:

Sharpless and Medal research groups discovered that a cycloaddition of an azide to alkyne could be catalyzed by Cu(I) species to give 1,4-disubstituted 1,2,3-triazoles. The potential of organic azides as a highly selective and energetic functional group is highlighted, and the dipolar cycloaddition [3 +2] with alkynes is among the most important tools in organic synthesis of new compounds. Triazoles have a wide applicability like medicines and pesticides. Considerable efforts have been made to develop protocols in the synthesis of these types of compounds.
