Abstract: Click Chemistry, as a powerful tool, has been used for the synthesis of a variety of
1,2,3-triazoles. Among click cycloaddition reactions, intramolecular click reactions carried out in
azido-alkyne precursors has not been thoroughly reviewed. Hence, in this review, we have summarized
and categorised the recent literature (from 2012 on) based on the azidoalkynyl precursor's
type and a brief and concise description of the involved mechanisms is presented. Accordingly, we
have classified the relevant literature into three categories: (1) substitution precursors (2) addition
and (3) multi-component reaction (MCR) products.
