Benzotriazole methodology, nowadays recognized as a versatile, useful, and most successful synthesis protocol, has grown from an obscure level to very high popularity, since benzotriazole can easily be introduced into a molecule by a variety of reactions, activates it toward numerous transformations, is sufficiently stable during the course of reactions, and finally can easily be removed at the end of the reaction sequence. In this review, we briefly describe the way benzotriazole methodology has grown to its present height, the opportunities and its potentiality in the synthesis of diverse pharmacologically important heterocyclic skeletons.
