Triazoles are five-membered aromatic heterocyclics, which could exist in two isosteric forms (1,2,3-triazoles and 1,2,4-triazoles) presenting huge applications in medicinal, agricultural, supramolecular and materials sciences. The drugs fluconazole, ribavirin, cefatrizine and tazobactam, and the herbicides cafenstrole and metosulam are famous examples of triazoles. The aim of this review is to present the main recent examples of Microwave-Assisted Organic Synthesis (MAOS) applied for the synthesis end functionalization of 1,4- and 1,5-disubstituted-1,2,3-triazoles, 1,2,4-triazoles, 3-amino-1,2,4-triazoles, 1,2,4-triazol-3-one and 1,2,4-triazol-3-thiol derivatives. Worth of noting, despite some previous reviews about triazole synthesis, none of them focused exclusively on the importance of MAOS technic in the obtention and derivatization of these compounds.
